Description:
------------
Dear PHP team

I have apache 2.2.14 , php 5.2.12 and mysql 5.1 running on XP.
Php and apache are fine when I test phpinfo() or other php commands which are not related to mysql. But when I try to connect to mysql, the apache sever crashes and the following error pops up:

Apache HTTP Server has encountered a problem and needs to close.  We are sorry for the inconvenience.

clicking for details I have this error signature:

szAppName : httpd.exe     szAppVer : 2.2.14.0     szModName : php5ts.dll     
szModVer : 5.2.12.12     offset : 0000ac6a 

I ran the code step by step, and I realize the problem is related to the line $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);

This is apache error.log after clicking "don't send" on the crashing pop-up:

[Sun Jan 31 04:03:57 2010] [notice] Parent: child process exited with status 3221225477 -- Restarting.
[Sun Jan 31 04:03:57 2010] [notice] Apache/2.2.14 (Win32) PHP/5.2.12 configured -- resuming normal operations

[Sun Jan 31 04:03:57 2010] [notice] Parent: Created child process 584
[Sun Jan 31 04:03:58 2010] [notice] Child 584: Child process is running
[Sun Jan 31 04:03:58 2010] [notice] Child 584: Acquired the start mutex.
[Sun Jan 31 04:03:58 2010] [notice] Child 584: Starting 64 worker threads.
[Sun Jan 31 04:03:58 2010] [notice] Child 584: Starting thread to listen on port 80. 


Reproduce code:
---------------
<?php
	session_start();

	require_once('config.php');
	
	$errmsg_arr = array();
	
	$errflag = false;
	
	//so far there was no problem. after this comment it crashes
	$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
	if(!$link) {
		die('Failed to connect to server: ' . mysql_error());
		
	}
.
.
.
?>

Expected result:
----------------
Connecting to mysql.

Actual result:
--------------
Apache HTTP Server has encountered a problem and needs to close.  We are sorry for the inconvenience.

Thanks for you attention.
I checked the link you provide but there was nothing there. It was just written "5.2 has no release" as well as other versions.

I have the exact same problem, same php/mysql/apache versions

Try with 5.2.13.

Also be sure that you don't have any other libmysql DLL in your PATH but the one we bundled in PHP releases. That may happen if you installed mysql after PHP.
