Description:
------------
PHP 5.2.5, MySQL 5.0.51a, for redhat-linux-gnu (i686) using  EditLine wrapper.

Running test script with correct user password, you will see:

Connected successfully.
[Thu Feb 28 18:04:59 2008]  Script:  '/home/bsg/www/t.php'
---------------------------------------
/home/user/php/ext/mysql/php_mysql.c(316) : Block 0x08f54820 status:
Invalid pointer: ((size=0x00000251) != (next.prev=0x00000000))
---------------------------------------

---------------------------------------
zend_mm_heap corrupted
Segmentation fault

First problem occured in php_mysql.c(316) in function _close_mysql_link on line "efree(link);". Second in zend_opcode.c in function destroy_op_array on line "efree(op_array->vars[i].name);".

If you change hostname or password to wrong, you will see another error:

Warning: mysql_connect(): Unknown MySQL server host 'localhost2' (1) in /home/user/www/t.php on line 2
[Thu Feb 28 18:09:24 2008]  Script:  '/home/bsg/www/t.php'
---------------------------------------
/home/user/php/ext/mysql/php_mysql.c(831) : Block 0x097db818 status:
Invalid pointer: ((size=0x00000251) != (next.prev=0x00000000))
---------------------------------------
Could not connect: Unknown MySQL server host 'localhost2' (1)

There is no segmentation fault now. But the problem is. In file php_mysql.c(831) the line is "efree(mysql);" in function php_mysql_do_connect.

Reproduce code:
---------------
%
<?php
$link = mysql_connect ('localhost', 'login', 'password');
if (!$link)
  die ("Could not connect: ". mysql_error ());

echo "Connected successfully.\n";
mysql_close ($link);
echo "Disconnected successfully.\n";
?>

[2008-03-03 13:12 UTC] jani@php.net

I can't reproduce this. Try running the script without loading php.ini using the '-n' option. If it still fails, provide the full configure line you used.

[2008-03-03 14:40 UTC] izh1979 at gmail dot com

The same thing with php -n. It doesn't depend on configure options. But last time I use:

./configure  --disable-cgi --disable-all --enable-debug --with-mysql

[2008-03-25 19:26 UTC] andrey@php.net

Hi,
can you try the following
USE_ZEND_ALLOC=0 valgrind php the_script.php

And post the result.

I can't reproduce it with 5.2 CVS

Hi,
I suspect that you have different headers for MySQL and compile PHP with one set and run with another libmysql. The valgrind problem is that mysql_init writes after the end of php_mysql_conn, which doesn't use a pointer but aggregates a MYSQL structure. This way, if you have compiled PHP with one header set and use different (later) libmysql, which thinks MYSQL is bigger, you get these errors.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.
