From:
Operating system: linux
PHP version: 5.3.8
Package: PCRE related
Bug Type: Bug
Bug description:PCRE segfault
Description:
------------
Tested this on my custom built 5.3.8 and the standard 5.3.8 that ships with

Run the test code - it will segfault. Not sure if this is PHP related (PHP
hooks into PCRE) or solely lives inside PCRE.
Test script:
---------------
<?php
$input = "
