I have found similar bugs, but can't find any acceptable solution.
In #47689 (did you mean this report?) I see tips to recompile php
(sorry, I use binaries only, don't have compilation skills), or patch
apache with VC Express (too large program. maybe there is some easier
way to patch it?)

You have to increase the stack used by Apache (so PHP's pcre won'r crash
due to a too smal stack). There is another report about this issue, with
an explanation about how to increase the stack of an executable (sorry,
I don't have the # at hand).

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);
?>
Actual result:
--------------
