Operating system: Windows XP SP2
PHP version: 5.2.8
PHP Bug Type: Reproducible crash
Bug description: calls to mysql_connect crash
Description:
------------
I have an isolated test case that reliably generates a segmentation fault
in php5ts.dll.
Here is the environment:
Windows XP, SP2, Single Athlon 64 3200+ CPU, 1 GB RAM
MySQL version 5.1.30 for Win32
Apache version 2.2.10 for Win32
PHP 5.2.8
PHP was installed with the .msi installer. The following extensions were
added at installation: GD, mysql, mysqli and multi-byte string.
I have configured Apache & MySQL and have created some databases, which I
can access through mysql and Navicat. I have used a simple phpinfo.php
script to track down an incorrect libmysql.dll in my path and have
eliminated that and have verified that the client version of libmysql is
5.1.30 in phpinfo.
Reproduce code:
---------------
<?php
mysql_connect('localhost', 'root', 'root');
print('Past mysql_connect');
?>
Expected result:
----------------
One expects to see the "Past mysql_connect" statement print out.
Actual result:
--------------
