In the PCRE block of my php.ini stands the same:
[Pcre]
;PCRE library backtracking limit.
; http://php.net/pcre.backtrack-limit
;pcre.backtrack_limit=10
;PCRE library recursion limit.
;Please note that if you set this value to a high number you may
consume all
;the available process stack and eventually crash PHP (due to reaching
the
;stack size limit imposed by the Operating System).

;pcre.recursion_limit=10

Check for these in your php.ini:
[Pcre]
;PCRE library backtracking limit.
; http://php.net/pcre.backtrack-limit
;pcre.backtrack_limit=10
;PCRE library recursion limit.
;Please note that if you set this value to a high number you may
consume all
;the available process stack and eventually crash PHP (due to reaching
the
;stack size limit imposed by the Operating System).

I'm using PHP 5.3.0 x86 VC6 Thread Safe. I have installed PHP 5.2.10
and can reproduce it too. After this i have installed PHP 5.3.0 again
without any extensions and have used a standard php.ini and httpd.conf
(just the entry from the PHP installer is written).
I have cleared the error.log from Apache and after executing the
reproduce code the log says:
[Thu Jul 16 02:40:03 2009] [notice] Parent: child process exited with
status 3221225477 -- Restarting.

But i figured out another thing. If I'm changing the pattern from
'#a((?:.|\n)*?)a#' to '#a((?:\n|.)*?)a#' all works fine. Oddly seems
that Avira AntiVir Personal with the definition file from the last days
and today says after saving the reproduce code that the file is a
heuristic found HEUR/HTML.Malware.

Exactly what PHP version are you using? This works fine on both 5.2.10
and 5.3.0 for me..

Description:
I found a regular expression with which i can restart the apache
service with the notification: [notice] Parent: child process exited
with status 3221225477 -- Restarting. I'm using Apache 2.2.11.
Reproduce code:
---
?php
preg_replace('#a((?:.|\n)*?)a#','a$1a','a11a');
?
Expected result:
I expected that preg_replace() repaces the string.
Actual result:
--
Apache restarts with the above message an Firefox 3.5 tells me that the
connection to the server was recessed.
