I've tried the latest CVS snapshot and this problem still occurs there.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Fwiw, I experienced the same error with the following code and the latest PHP.

...
for($i = 0; $i < $foo; $i++) {
 ...
  for($i = 0; $i < $bar; $i++) {
    ...
  }
  ...

Same problem here.

I'm trying to use horde-imp but "zend_mm_heap corrupted" problem occurs when I open admin/setup/config.php?app=imp to configure the app and the browser offers to download config.php file.

Please devs give us a working patch :)

We still don't have zero info on how to reproduce it.

Hi
 
I get the same message in my logs. I can reproduce the error in our system, but it is impossible to locate it. Sometimes I can reproduce the error by editing a comment. I add a character and the error occurs. I remove the character and the script runs perfectly. Each time I try to isolate the error I can reproduce it with an other action.

That what i could isolate is:
-load xml file with simplexml
-add a node
-clone the object
-process xpath query
-print the object with print_r
-serialize the object
-include a file (the error occurs)

When I edit the included file. E.g. remove methods or properties the script runs without errors. That is funny(o;

I'm experiencing the very same problem reported by rocker_pr.

It seems to me that this problem is triggered by using PHP5 classes, but I can't provide a small testcase: no small code seems affected.

Hi,

i too got the same issue and this is how the code works,

I am having some scripts to parse the HTML data and wherein i am having part of the code as ,

				$replaced_key = strtolower(str_replace("%", "percent", $key)); 
				$replaced_key = str_replace(".", "", $replaced_key); 
				$key = str_replace(" ", "_", $replaced_key); 


When i have the above code with the same variable name,

				$key = strtolower(str_ireplace("%", "percent", $key)); 
				$key = str_ireplace(".", "", $key); 
				$key = str_ireplace(" ", "_", $key); 

I get the "zend_mm_heap corrupted" error wherein when changed the code to the above way, it works fine.

I found this 'zend_mm_heap corrupted' in my apache log files.

I am using 5.2.5 with almost everything enabled. Mysqli and I am using Zend Frame work.

As far as I can tell my scripts case this (and a seg fault) when they are looping through a Zend_DB_Table_Rowset object adding rows to a table.

When the $row **goes out of scope** the script seg faults. So I get this error when the function (well method) returns a value. I stripped all code from the function apart from echos and the $row->save() and the seg faults still happen.

Ho hum...

 [2008-07-16 16:38 UTC] john dot glazebrook at guava dot com
Sorry, I forgot to say my server runs Red Hat Linux.

Um, I'm not sure if this is helpful, but I found the error when moving from PEAR:DB over to ZF DB objects. So I only changed DB code. OK, some psedudoish code:

class x {
  function db() {
    $rpt = new Report();
    $row = $rpt->createRow();
    $row->text = 'xyz';
    $row->save();
    echo 'OK 2';
  }
}

$x = new x();
echo 'OK';
$x->db();
echo 'OK 3';

And I see:
 OK
 OK 2
 seg fault

Also changing the function to:

class x {
  function db() {
    $rpt = new Report();
    $row = $rpt->createRow();
    $row->text = 'xyz';
    $row->save();
    echo 'OK 2';
    $row = null;
    echo 'Moooo';
  }
}

this time it seg faults at $row = null;

Hope this is of some help. It really sucks :-(

 [2008-07-17 08:28 UTC] john dot glazebrook at guava dot com
OK, I don't know if this is useful but I'll keep posting stuff as I find it here :-)

PHP 5.2.5 MysqlI 5.0.45

If I alter the database the seg fault goes away and I get normal exceptions or errors or data results (depending if the SQL is working) then if I change the DB back to what I need seg faults occur again. So I think it must be an error in MysqlI or MySQL... ?

This happens no matter what version, 5.2.1, 5.2.6 and even 5.2.7-dev (snap php5.2-200807220430)

How is it possible this many users have this bug, some even can reproduce it consistently, and the developers need backtraces?  It seems as though it is a common bug and my guess is many come here looking for a solution, do not find one, figure the zend_mm_heap corrupted is intermittent and hope for a solution soon (they do not post they too have the issue).  

I will attempt to recompile with debug and get a trace, however, this only occurs on production servers (indicating load/stress related issue when using more memory) and will take a while to get the OK to execute.  Running one of the scripts provided below to reproduce the crash does not happen for us on development systems.

this bug is over 16 months old and when it happens, it is a whopper, please do not ignore!

will be happy to provide any additional information that does not require a recompile/waiting for clearance on production.

Concerning my previous statement: I was using output buffering in the included files. I've removed the output buffering and I'm no longer getting the error.

report and change the status back to "Open". Thank you for helping
us make PHP better.

Also, all problems reported here have different causes but seems to be
triggered when starting to use more memory, and the bug disappears
when using less memory, or by changing/commenting a random line in
your code.
 
For me it looks like a hardware problem (dead memory segments), please
use a memory testing tool (e.g. memtest86 [1]) or try to reproduce the
bug on an other computer. Dead memory segments can cause exactly that
sort of problems (corrupted memory, crashes, etc).

(See my previous messages posted above...)

I just tried my code on a brand new HP server, this time on CentOS 5.2, PHP 5.2.0, MySQLI 5.0.45.

I still get seg faults in httpd error logs files.

So I don't see how this is a hardware fault. I see this error using the same PHP code on 3 different servers, 2 different operating systems and 2 different MySQL versions. I also changed my tables from MyISAM to InnoDB and *STILL* get seg faults.

I use Zend Framework and I have changed DB adapters from Mysqli to PDO_MYSQL, but both cause seg faults. Does that cover everything apart from the PHP version?

Um, one more thing. As a programmer of 10+ years having programmed about 7 or 8 languages seriously over that time, this feels like a race condition.

Occasionally the page request works. Putting in sleep commands effects where in the script it crashes. Attaching the debugger and slowly stepping through the code causes it not to crash.

Thanks for the backtrace.
It seems you are using a third party extension, could you please provide a backtrace with all third-party extensions disabled ?

hello?

We are experiencing multiple zend_mm_heap corrupted errors daily on our production server during peak load.

During off-peak periods, all scripts work as expected.

PHP 5.2.2
RedHat Linux 2.6.9-78.0.5.ELsmp

Why is this set to No Feedback when there's a debug dump provided?
 [2008-11-20 09:06 UTC] john dot glazebrook at guava dot com
The more comments the more this sounds like a race condition. Looks like it would be almost impossible to bug hunt.

Have you tried the 6 version? Maybe this has been fixed?

After my debugging - it seems script runs to the end (trigger_error even in last line works). Adding one

print(null);

in random place of script did help me! But I had this problem for 3 places, it help only for one. And now is the best :) Huge block of

print(null);print(null).....

is enough in my case :)
I only have hope - my customer will not look into source ;)

On the other hand now i had a lot of

[notice] child pid 29716 exit signal Segmentation fault (11)

in log, but at least it sends output befor exit,so I can live with it ;)

We started seeing annoying random crashes in quite large app after upgrade to Ubuntu Hardy (32bit). PHP Version 5.2.4-2ubuntu5.3

This is starting to be quite serious issue.
 [2008-12-12 16:48 UTC] yell at yellow1 dot pl
ok, zend crashes at the end, when it has to send data from buffers and free memory. so best solution is to flush buffers on your own. it's enough to put in last line:

ob_end_flush(); flush();


this bug was found for the first time almost 2 years ago. maybe it is hard to track, becaus it appears only in bigger aps with a lot of php5 classes, but... 2 years? and still no idea what is going on? even more - claiming there is no problem at all, only because it's impossible to recreate this bug in 20 lines of code? for me - php after so many years of development is still so unstable, it simply no longer exists, sorry...

I have run into this problem too. I have not been able to make a short example script to demonstrate the problem since removing seemingly unrelated parts of code makes the problem disappear.

The error is generated after the PHP script has completed. The actual problem seems to stem from calling a some static method from a class that has not yet been included. The class is included by an __autoload function. Manually including the class first seems to fix the problem, but doing random stuff in general seems to do that :)

The problem occurs when returning from the function, since throwing an exception or die()-ing at that point does not show the problem.

When building php with --enable-debug, the problem goes away. The problem also goes away when not using --enable-debug, but adding -DZEND_MM_HEAP_PROTECTION.

Since the problem goes away when using --enable-debug, I generated the following backtraces with a modified zend_mm_panic(...) in zend_alloc.c to remove the #if ZEND_DEBUG macro.

This script may help to reproduce the bug.
It is a stupid script, but sometimes the two
generated files (teste.txt, teste1.txt)
are different. But they should be identical.

<?php
file_put_contents('teste.txt', str_repeat("ABCDEFGHIJKLMNOPQRSTUVWXYZ\n", 10000));

$output = file_get_contents('teste.txt');

for ($n=1; $n<=10000; $n++)
{
    $output = str_replace('G', 'G', $output);
}
file_put_contents('teste2.txt', $output);
?>

Interestingly enough, changing values in php.ini helps:

Apache/2.0.63 (Win32) PHP/5.2.8

FWIW, this happens when running as a service.  Running in the console it's fine.

I found it in response to bug #46842, after rolling back from Apache/2.2.  I cannot say for sure if they are related.

The same problem appears from a allegedly successful compilation op PHP 5.2.9 on RHEL5 64 bit using -m32 CFLAG so that the binaries are 32 bit.

The compilation appears to complete successfully:


Apache 2.0.59 compiled w/o any problems with the following configure and it works fine.
./configure --prefix=/apps/apache2 --with-expat=builtin

PHP is configured with the following options:
./configure --with-apxs2=/apps/apache2/bin/apxs --build=i386-redhat-linux --with-pic --with-gd --with-zlib --with-config-file-path=/apps/apache2/conf --with-libdir=/lib/ --enable-debug

And after the successful run, make test was run with the following errors:

I think this is because the configure script assesses the intmax_t as 4 as opposed to 8 and all of the integers are overflowing with 4 bytes. Just a guess but comparing to an other environment where I managed to compile it successfully, these appear to be the main differences in config.log.

Ran into the same problem and read most of the posts in this report. Well, I don't expect PHP developers to ever find this bug. Don't you get annoyed by template-driven posts asking for information they can't use?

HERE COMES MY ADVICE: Reading hints on expecting a race condition lead me to installing suhosin, which is an extension to PHP increasing its integrity and security. Guess what, it helped me out of this trouble. This is no ad, so I won't provide a link here. Just google the name ...

Maybe PHP developers shouldn't use templates requesting tons of backtracks providing obviously useless information, but invest some time in revising observers for the internal memory management of PHP as this is obviously causing the trouble.

Soletan, thanks for advice but it seems that Suhosin is not 100% solution. We are running Ubuntu Hardy (8.04 LTS) server, 32bit. Using standard PHP 5.2.4 Apache2 module package which already includes Suhosin patch. We still experience this bug...

I'm surprised this isn't being talked about more. I see it occasionally, and I am using Zend Framework. Why don't other people using ZF see it?
 [2009-03-13 10:57 UTC] dwdkl dot pub at o2 dot pl
I have this problem too.
Configuration: PHP 5.2.8 (Win32), Apache 2.2.11, MySQL 5.1.31, OS WinXP.
I have this bug, when i try run phpmyadmin (all versions). Apache restarted and i found in apache's logs the message "zend_mm_heap corrupted".

Sorry, my english is weak ;-)

Apache 2.0.x - problem does not occur.

Hello,

This is the first time I see exactly the same message you all have.
You may use an accelerator (such as eAccelerator, I saw many results for this error on their forums).

Personally, I try to use the Zend Accelerator and Loader provided by the Zend Platform 3.6.2 and it fails (Fatal Error on accessing an object as an array... although it implements the ArrayAccess!). Yesterday evening, I tried to blacklist the supposed 'bad' file and got the famous error 'zend_mm_heap corrupted' :)

I soon as I disable the 'Code Acceleration', I got no troubles. It seems it's not due to the PHP Core, but maybe a change on it that has broken the third party accelerators...

Voila :),

Hello,

I too have been able to recreate this bug with php 5.2.9

It occurrs when UPGRADING from Mysql 5.0.45 x64 el5 to Mysql 5.1.x x64 el5. (mysql 5.1.25 5.1.30 5.1.33 5.1.34

The error occurrs when I recompile PHP against the new Mysql-devel 5.1.x header files.

I've tried compiling against the native PHP mysql libraries and also specifying the mysql libraries in /usr.

I believe that the heap error occurrs due to a debug necesity becuase I followed the advice of a previous comment(THANK YOU!!!!) I placed enable-debug in the configure command and IT WORKS!

I can't pin it down for sure but there is some incompatibility with mysql 5.1.x and the php-mysql extension that calls a function from the debug extension.

I think the solution lies in checking the mysql extension in PHP and finding where the debug function is called and only calling with the debug extension enabled / loaded.

Hi,

Just to echo the previous comment, I have experienced the same crash with PHP 5.2.9-2 under Win32 (Server 2003 R2), when upgrading the MySQL DLLs from 5.0.77 to 5.1.34. I am bypassing the copy of libmysql.dll provided with PHP in order to work around another bug, and I found that when I upgraded to libmysql.dll 5.1.34, PHP crashed out with the 'zend_mm_heap corrupted' error when running certain scripts (especially ones that access MySQL, like phpMyAdmin), which in turn caused IIS to error out with 'CGI Error: The specified CGI application misbehaved by not returning a complete set of HTTP headers.'

The issue is resolved if I copy libmysql.dll version 5.0.77 into my PHP path, which indicates that this may be one of the causes of the problem.

I can reproduce this bug reliably.
 [2009-06-24 23:14 UTC] BAReFOOt at mailinator dot com
Well, I we mysql, the installed webapp (mediawiki) is not using it, it's version 5.0.70, we got the debug extension enabled, and we still get the bug.

It crashes the whole apache (2.2.11) instance! We don't have any special PHP extensions on it.

But frankly, by knowing the quality of the Zend engine code itself, I do not have any hopes that there is anyone who works on that code, and is even remotely able to fix this. :P
I recommend switching to a real language, and stop using this VisualBasic of web languages. :/

Sorry, after all this time, (255 days, or 8.5 months!), I have no good words for this anymore. It basically makes PHP useless, and any new PHP development (webapps), are now completely out of question in our company.
 [2009-06-24 23:31 UTC] rasmus@php.net
This has turned into a catch-all bug report for any generic memory corruption, not even necessarily in PHP itself.  It could be a 3rd-party library stomping on memory as shown by some of the reports of things going away when upgrading a lib.  As a single bug report it isn't of much use to us, but the backtraces to help and might point us to an actual problem in PHP.
 [2009-07-30 06:22 UTC] laurynas dot butkus at gmail dot com
Finnally, found solution on Ubuntu Hardy.

Add line:
export USE_ZEND_ALLOC=0

to file:
/etc/apache2/envvars

and restart apache... Crashing stopped.
 [2009-08-10 20:53 UTC] asilentpenguin at yahoo dot com
On Fedora / centOS

edit:
/usr/local/apache2/bin/apachectl

and add:
export USE_ZEND_ALLOC=0

and stop & start apache.

P.S.: i think you are underestimating the number of occurences for this bug and, as so, the frustration amongst PHP developers
 [2009-09-17 15:32 UTC] tdikarim at hotmail dot com
Hi all,

Someone have the solution for os windows XP

thanks
 [2009-09-17 18:13 UTC] sriram dot natarajan at gmail dot com
to answer tdikarim at hotmail dot com's question, you can probably add

set USE_ZEND_ALLOC=0 within your apachectl.bat under your apache 
installation directory /bin. not, for this to work, you should start 
apache from command line and not as a 'service'. also, may I suggest 
that you probably try to run with php 5.2.10 or php 5.3 (from 
windows.php.net) and see if you are able to reproduce this issue 
before you consider using the work around (using USE_ZEND_ALLOC). 
please note that using USE_ZEND_ALLOC=0 will have some performance 
penalty. 

now, looking closely into this bug, as Rasmus mentioned earler, this 
bug has become a catch-all for memory corruption.

looking at the some of the stack traces and with so many people have 
reported this , this is probably a valid bug and we would love to fix 
this issue provided some one can provide us a script (even if it is 
complicated) that any one of us can reproduce. this would quickly help 
us to get to a solution. 

some of the folks have mentioned that they use redhat / fedora but 
have failed to mention whether they are using php with apache's pre-
fork (which is fortunately the default )mpm or worker mpm . 

(note: if you don't know what is worker mpm, you are most likely using 
the default pre-fork mpm !).  

why is this important ? - this is because if you are running your 
apache in threaded mode but if php is not compiled with 'thread-
safety' option, then one can run into lot of weird race condition. but 
with pre-fork apache, you very rarely run into a race condition. 

so, please when you report this crash, please provide us the php 
version and is it compiled with ZTS (zend thread safety) enabled  and  
is your web server multi-threaded. for example, you can get apache's 
server information by running 'httpd -V' from your linux box.
 [2009-09-18 07:39 UTC] tdikarim at hotmail dot com
I bring some additional information.
The error occurred with the version of PHP 5.2.1 and version 2.2.13 of Apache.

This is done by creating a large PDF to do more than 35,000 pages using File_pdf (last release) PEAR.

I just installed version 5.3 and I'm going with this test without using USE_ZEND_ALLOC.

For your information, I find pale apachectl.bat file in my apache directory.

I install apache and php via EasyPhp v2.0.0.0
I advise you to install something else?

I will keep you informed of my test with version 5.3. It will take a few hours

Again thank you
Karim
 [2009-09-18 08:24 UTC] tdikarim at hotmail dot com
Hi ,

I have tested with the version 5.3 of PHP with no success.
I have this error:
Fatal error: Out of memory (allocated 564920320) (tried to allocate 39063398 bytes) in I:\srvDevPHP\PHP_PEAR\File\PDF.php on line 3191
zend_mm_heap corrupted
The line 3191 is << $this->_buffer .= $s . "\n"; >> of the _out function.

How can i use the USE_ZEND_ALLOC parameter. I don't find any file for do that.
Somme info:
EasyPhp 2.0.0.0
     php 5.3.0
     Apache 2.2.13

Thanks

I see this error all the time on my complicated application.  I am using php-fcgi + nginx + mongodb so I am fairly sure it is something in core.

I find that even a small change can fix the problem, output buffering seems to be the culprit for me (ob_end_flush() seems to fix it) which is maybe why people can only reproduce on production servers?

I can confirm, that my apache crashed with the error "zend_mm_heap corrupted" under heavy load. After that I get a lot of Segmentation faults (11).

OS: CentOS 5.4
PHP: 5.2.11 
Apache: 2.2.14

The server is running as a virtual machine in an ESXi 3.5 Server.

I'm now testing the "export USE_ZEND_ALLOC=0" workaround in my apachectl. I'll provide more feedback as soon as I know if this helps.

Adding 
export USE_ZEND_ALLOC=0

Just for history/logging purposes, I got this same error on PHP 5.2.6 + MySQL 
5.1 + Apache/2.2.4 (Unix) mod_ssl/2.2.4 
OpenSSL/0.9.7a DAV/2 + SuPHP on RHEL 4 today. 

It was related to mysql_* calls, phpinfo() worked fine, no errors. Any mysql_* 
call crashed.


Code:
---------------
[eromero@roll tmp]$ cat /tmp/test.php 
<?php 
echo "Hola";
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($link);


Reproducing
---------------
[eromero@roll tmp]$ /usr/local/php5-cgi/bin/php-cgi /tmp/test.php 
zend_mm_heap corrupted


Worked fine with USE_ZEND_ALLOC=0 
---------------
[eromero@roll tmp]$ export USE_ZEND_ALLOC=0
[eromero@roll tmp]$ /usr/local/php5-cgi/bin/php-cgi /tmp/test.php 
PHP Warning:  mysql_connect() [<a href='function.mysql-connect'>function.mysql-

Updating to 5.3.2 fixed the issue.

both times. Disregard the unused flags:

Problem:
----------
I had this problem when importing an xml file with over 4200 items which all needed inserting as individual records into a database.

I was using doctrine to insert the records and was creating a new object for each record, but each time I ran the script it crashed with this error after inserting exactly 3,579 records each time.

 Solution:
-----------
I then decided to try cleaning up the code I had written by using unset() to destroy the object after it had been finished with. All of the records were then inserted without any problems.

I would advise anyone receiving this error to check that variables and objects are being destroyed with unset, because if you think about it the error is telling you that the zend memory managers heap is corrupted.

I had it coming when I started my unittests. But it happened out of nowhere ^^
Wehen I set USE_ZEND_ALLOC=0 it didn't go away, but instead I got a debug backtrace (as seen below). But I came up with a solution: ZendDebugger was the root of all evil. I'll check out if there's a newer version available...

The problem is still in 5.3.3 on Suse 11.2, but it is not reproducible :-(
Sometimes it is twice a day sometimes every few days.

Apache starts giving these messages:
"child pid xxxxx exit signal Segmentation fault (11)"
And if your are lucky, the scripts still return xml-results.
If you get a no result from the script (i.a. white page in browser),
you'll need a apache stop and start (graceful does not help)
and the error_log says:
"seg fault or similar nasty error detected in the parent process"

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.


 [2011-08-31 07:49 UTC] f dot ardelian at gmail dot com
The cause is pretty clear to me: when the script ends, the garbage collector starts to destroy the objects and the `unset()` in the destructor probably invokes the garbage collector again. The error message doesn't always appear on the screen nor in the error log (sometimes it does). The "Segmentation fault" always appears in the error log. Breaks if PHP is installed using apt-get or yum or comes with your Linux distro. Seems to work fine on Windows and codepads (custom compiled PHPs). Definitely breaks on Debian. Don't forget to set memory_limit to have enough room in memory to create all the objects (128M seems to be enough on Debian to create 150,000 objects).

<?php
define('OBJECT_COUNT', 20 * 1000);

class Object {
    private static $world = array();
    private static $maxGuid = 0;
    protected $_guid = null;
    public function __construct() {
         self::$world[$this->_guid = self::$maxGuid++] = $this;
    }
    public function __destruct() {
         unset(self::$world[$this->_guid]);
    }
}

for ($i = 0; $i < OBJECT_COUNT; ++$i) {
    new Object();
}

// You probably won't see this because of the "zend_mm_heap corrupted"
echo 'If you see this, try to increase OBJECT_COUNT to 100,000';
?>

If this code pinpoints the four and a half years-old issue, email me a beer.

I must agree with Florin, we are experiencing the same kinds of issues, both with 
CLI and mod_php, su_php and across 5.2.* and 5.3.*. We really need this to be 
fixed. Any updates?

problem solved by compiling apache with prefork. Somehow Apache worker MPM + PHP 5.2 works fine but Apache worker MPM + PHP 5.3 fails terribly. Prefork seems stable
 [2011-11-02 10:34 UTC] from dot php dot net at brainbox dot cz
I can reproduce the bug on Microsoft Windows XP SP3, with latest official PHP 5.3.8 NTS build.

When we run script from "f dot ardelian at gmail dot com", PHP does not output "zend_mm_heap corrupted", but right after displaying the "If you see this…" line CRASHES.

However, I found that when I call "gc_disable();" before script end, it finishes successfully. This helped me run the test script without problems, but didn't solve the issue in my other scripts.

<?
define('OBJECT_COUNT', 100 * 1000 * 10);

class Object {
    private static $world = array();
    private static $maxGuid = 0;
    protected $_guid = null;
    public function __construct() {
         self::$world[$this->_guid = self::$maxGuid++] = $this;
    }
    public function __destruct() {
         unset(self::$world[$this->_guid]);
    }
}

for ($i = 0; $i < OBJECT_COUNT; ++$i) {
    new Object();
}

// You probably won't see this because of the "zend_mm_heap corrupted"
echo 'If you see this, try to increase OBJECT_COUNT to 100,000';

gc_disable(); // ADDED - works for me - PHP does not crash

Hello, I use Wordpress. I am hosted in home.pl which uses IdeaWebServer instead 
of Apache. Very often when I enable whatever cache plugin I get the 
"zend_mm_heap corrupted" error.

I have also a hosting in the USA with Apache and the same PHP and MySql 
versions. If I backup both data and database and restore it in the Apache server 
I can use my caching plugins without issues because the "zend_mm_heap corrupted" 
error never appears.

Home.pl says that this is a PHP issue and it is not connected with their non-
Apache server.

What's your opinion in that? Is it a PHP issue or a hosting issue?
Thank you

"f dot ardelian at gmail dot com" test case works on php 5.4rc2, too (php 
cli segfaults)
 [2012-02-20 20:05 UTC] andreyvit at me dot com
Just had the same issue, but 100% reproducible. It does not always print 
zend_mm_heap corrupted, but it always segfaults PHP.

I've traced it to an equivalent of the following two lines of code:

  $xx = new stdClass;
  strpos($xx, ':');

Moreover, this only crashes inside a custom error handler function. If I disable 
set_error_handler call, the crash disappears. The crash inside the error handler 
is on a pretty innocent operation, and the location is not stable (most often it 
crashes on assigning a large literal array to a static variable).

I tried to produce a smaller test case which reproduces the crash, but failed. 
Some magic dust is always missing.

However, this gives us an alternative theory why most people may only be seeing 
this in production and rarely: they may only be running a custom error handler in 
production, and they may have a rare critical error somewhere which can trigger 
it. Try disabling your error handler and see.

I have just run into the same problems after upgrading from 5.2.17 
to 5.3.10 last weekend. Hosted on Debian server. Before I found this 
bug report, I created another one:
https://bugs.php.net/bug.php?id=61508
, which now seems to be a duplicate of this one.

It is true I have a loaded server with many extensions and many 
users with their own apps, so this seems not to be possible for me 
to check all their code or to downgrade to unsupported 5.2 branch.

Hi,
I used the USE_ZEND_ALLOC=0 and got another segfault. But in this case in the apache error log is hopefuly something useful:

I've also confirmed the above testcase triggers it on 5.3.10 via CLI. Can provide 
full access to any php developer interested in taking a look, just email me.

Also to add, USE_ZEND_ALLOC=0 did not resolve but gc_disable(); did
 [2012-04-02 13:41 UTC] komanek at natur dot cuni dot cz
For me it seems the solution is to compile PHP with

--disable-zend-multibyte

instead of

--enable-zend-multibyte

But I am not sure if it breaks something else, I didn't find much 
documentation on these options.

[02:48] <@nikic> I think user comments should be blocked and there should be 
some big message at the top saying that people should report separate bugs for 
their issues
 [02:48] <@nikic> So if someone can edit the report to include a message at the 
top that would be great
 [02:48] <@nikic> It doesn't really help a lot if all zend_mm_heap corrupted 
reports go into one bug ^^
