Description:
------------
After I use the XSLT extension to process a huge file, I got an error on the Apache error_log and a blank page on the browser. The error is:

*** glibc detected *** double free or corruption (fasttop): 0x08236cc8 ***
[Wed Feb 01 08:56:12 2006] [notice] child pid 7121 exit signal Aborted (6)

Reproduce code:
---------------
http://pastebin.com/533629

Expected result:
----------------
A regular HTML page and no error on error_log.

Actual result:
--------------
Sometimes it becomes blank and after some realoading it works, but *always* with an error message on error_log.

I tested the code on all the ways I could but the only solution was downgrade PHP to 4.4.2 with Sablotron support.

Then everything run fine (same Apache version, same OS), the only negavite thing is that it takes a lot of time to show the results on the browser, while using PHP 5.1.2 it was very fast.

To reproduce it we need test.xsl either.

[2006-02-01 14:05 UTC] eustaquiorangel at yahoo dot com

The test.xsl code is also there on the URL, on the end of the PHP code.
One interesting thing: I installed right now PHP 5.1.1, and it's working fine! Not so fast as PHP5 (the same speed as PHP4), but no more double frees.

[2006-02-01 16:19 UTC] tony2001@php.net

Please try using this CVS snapshot:

  http://snaps.php.net/php5.1-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.1-win32-latest.zip

Works fine here.

[2006-02-01 17:24 UTC] eustaquiorangel at yahoo dot com

No way to avoid it with 5.1.1 +. :-(

I downloaded the snapshot you told me, installed (phpversion() gives me "5.1.3-dev") and when running the sample, it shows me again the error_log message:

*** glibc detected *** double free or corruption (fasttop): 0x082392a0 ***
[Wed Feb 01 14:10:20 2006] [notice] child pid 11636 exit signal Aborted (6)

I'm checking http://www.php.net/ChangeLog-5.php and seems that on the Windows version there were some changes:

# Updated to libxml2-2.6.22 and libxslt-1.1.15 in the win32 bundle. (Rob)

It's exactly the same versions I'm running here on Linux.
And there were some little stuff like

# Added constants for libxslt and libexslt versions: LIBXSLT_VERSION, LIBXSLT_DOTTED_VERSION, LIBEXSLT_VERSION and LIBEXSLT_DOTTED_VERSION. (Pierre)

that would not affect this way the behaviour.

I did some diffs with the ext/xsl 5.1.1 and 5.1.2 files but didn't find some relevant changes, just comment changes.

Now I downgraded again to 5.1.1 and it's working fine again, no errors. Could you test the code on a Linux computer?

[2006-02-01 17:30 UTC] rrichards@php.net

Can you get a backtrace? It's working fine for me on both win and linux boxes. does it crash under cli too?

[2006-02-01 18:20 UTC] eustaquiorangel at yahoo dot com

On CLI it seems that is not a problem. I run it 10 times and no error message. And using the web server seems that it's not a problem too, *** till *** (and I saw this now) I opened a script which gives me acess to our local intranet and it uses a simple database connection. Then the message is shown!

I just saw that because I was testing on the CLI, on the "pure" webserver script and then I connect to get my report, and, voila, the error message is there.

Maybe a problem on the database code and not on XSLT (that seems to works ok isolated)? Or maybe both? XSLT could put some junk on the memory and the database stuff just gives the error? Wow. 

I'm using Oracle Instant Client here. And, again, no error with any of those stuff on 5.1.1.

[2006-02-01 19:34 UTC] tony2001@php.net

We can't reproduce it, so you tell us.

[2006-02-01 20:13 UTC] eustaquiorangel at yahoo dot com

> We can't reproduce it, so you tell us.

Too many variables there, but definitely something is different from 5.1.1 to 5.1.2. To reproduce it the way we have here you'll need the exactly the same environment, but this is a complicated matter. OS, Apache version, all the scripts needed to run our environment. 

As I'm trying to make this works since before yesterday, I can't wait more to put the computer to work. I'll stick with 5.1.1 (ooofs, it's working fine) and if on the next upgrade (I'll skip 5.1.2 for sure! ;-) it happens again I'll open a bug report again, hopefuly with more time available to spend to check it. You can close this report.

Btw, I understand that reproduce the problem helps a lot, but since it's my first bug report here, I'm curious: thinking about all the scripts installed on all over the world, how can you dig more into this kind of thing without having the same enviroment?

[2006-02-01 20:23 UTC] tony2001@php.net

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Just an added data point:

I'm getting this same crasher, but only when mod_fastcgi is enabled (not even using a PHP script--but it appears to happen when PHP is being loaded by fcgi).  Here's the pseudo-backtrace from the log (I'll try to reproduce it in gdb later):

[2006-02-27 20:48 UTC] joe at virtualmin dot com

I was wrong.  FastCGI was not involved.  In my case, it was happening because both mod_php4 and mod_php5 were being loaded into Apache.  Removing one of them resolved the issue.

I have the same Problem on two different Server, but I'm don't using XSLT.

Here are the Logs.
