Sorry, no clue how to get a backtrace on a running system.
This httpd -X does not work. Not even mod_backtrace.
Simply
Download the Text_Wiki with Mediawiki and parse some large Table. You
get the error then yourself. I really doubt its system related.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php
for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Description:
------------
When i do this Regex
#^\{\|(.*?)(?:^\|\+(.*?))?(^(?:((?R))|.)*?)^\|}#msi
on larger requests, it causes a seqfault.
You just need to be some chars above some kind of limit and you got the
error.
Reproduce code:
---------------
http://cvs.php.net/viewvc.cgi/pear/Text_Wiki/Text/Wiki/Parse/Mediawiki/Table.php?revision=1.11&view=markup
Its Text_Wiki_Mediawiki.
Expected result:
----------------
HTTPD Seqfault
