Description:
------------
Test script crashes on web server (Apache 2.2.21) only with "empty response"
(324). Suspected to be a limit/overflow problem since it works if "errorerror" is
replaced with "error".
Test script:
---------------
<?php
echo preg_match( '/^<a(.)+class="(.)?actor-link(.)?"(.)+>Super
User<\/a>/', '<a class="actor-link"
href="/errorerror.lv/lv/jomsocial/42-super-user/profile">Super User</a> added 2
new photos in <a
href="/errorerror.lv/lv/jomsocial/42-super-user/photos/album?albumid=1">crap</a>
album' );
echo "\nFINISHED!";
?>
Expected result:
----------------
"1\nFINISHED"
Actual result:
--------------
HTTP error 324: empty response. Probably PHP crash. Apache didn't crash.
