Description:
------------
This issue seems to have some history at bug 26286 but that bug no longer exists so I cannot tell if a resolution was found for it.

The reproduction code does not seem to be the only way this crash is caused, but it is the only one I can find that will consistently reproduce the problem.

So if this is a duplicate of 26286, at least what was the resolution?


Reproduce code:
---------------
<?php
$value = "";
for( $a=0; $a < 1561; $a++ ) {
	$value .= "t";
}

$res = preg_match(
'/(?:(?:(?:(?<!\\\\)(?:[\\\\](?:[\\\\]{2})*))+[\$])|[^\$])*/', $value
);
?>

from bug 37397

Expected result:
----------------
apache not to crash
php error thrown

Actual result:
--------------
apache crashes:
[Wed Oct 04 15:41:14 2006] [notice] Parent: child process exited with status 3221225477 -- Restarting.
