Description:
------------
This script causes apache crash.
In CLI this script works well, so I put it as apache related bug.
Bug is reproducable with php versions:
5.2.14
5.2.13
Bug is NOT exists in php 5.2.6

Bug is reproducable with any php.ini config, including my own configuration, "php.ini-dist" and "php.ini-recommended"

I'm using Apache/2.2.8 on Windows XP SP3
and Apache/2.2.11 on Windows Server 2003
Bug is reproducable on both.
PHP is configured as php5_module with php5apache2_2.dll (dll is from original PHP zip package for win32).

Summary:
PHP 5.2.14 + Apache/2.2.8 + Windows XP = CRASH
PHP 5.2.14 + Apache/2.2.11 + Windows Server 2003 = CRASH
PHP 5.2.13 + Apache/2.2.8 + Windows XP = CRASH
PHP 5.2.6 + Apache/2.2.8 + Windows XP = OK
PHP 5.2.6 + Apache/2.2.11 + Windows Server 2003 = OK

Test script:
---------------
<?
$preg="\<td\>((?<!\<\/td\>).)*";
$str="<td>bug appears only with a long text here bug appears only with a long text here bug appears only with a long text here bug appears only with a long text here bug appearsbug appears only with a long text here bug appears only with a long text here bug appears only with a long text here bug appears only with a long... exactly this size.</td>";
//at least 343 bytes (334 bytes without tags)
preg_match_all("/$preg/", $str, $m);
?>
