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:

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.
