Bug description: Segmentation Fault with preg_match_all
Description:
------------
Good morning,
executing preg_match_all() function with this Regular Expression causes a
PHP Segmentation Fault.
The following code works correctly both with previous versions of PHP and
PHP 5.2.1.
Thank you for support
Adriano C.
Reproduce code:
---------------
<?php
$pattern =
"/\s([\w_\.\/]+)(?:=([\'\"]?(?:[\w\d\s\?=\(\)\.,'_#\/\\:;&-]|(?:\\\\\"|\\\')?)+[\'\"]?))?/";
$context = "<simpletag an_attribute=\"simpleValueInside\">";
$match = array();
if ($result =preg_match_all($pattern, $context, $match))
{
var_dump($result);
}
?>
Expected result:
----------------
int(1)
Actual result:
--------------
Segmentation Fault
