PHP version:      5.2.11
PHP Bug Type:     Scripting Engine problem
Bug description:  preg_replace cause Apache error and retart.

Description:
------------
When I execute a sql by Zend DB, I got a connection error, 
and found an error in apache error log. 
After tracking, I found the problem is preg_replace function.
I think you can replay this problem by the test code.

Env:
 Windows XP, Windows Server 2003
 Apache 2.2.13
 PHP php-5.2.11

 

Reproduce code:
---------------
function testPregReplace() {
        $sql = "SELECT \"t_skill_label\".\"c_name\" FROM \"t_skill_label\" WHERE
(\"c_name\" =
'‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨')
AND (\"c_id\" != '3') LIMIT 1";
        echo preg_replace("/'(''|\\\\{2}|[^'])*'/", '', $sql);
}
testPregReplace();


Expected result:
----------------
Apache not be restarted.

Actual result:
--------------
This test code will cause apache error. 
You can confirm it in the apache error log.
The browser display a connection error.
