Description:
------------
The statement in the reproduce code simply crashes my server (Win XP
Pro, Apache 2, PHP 5.1.0, default-charset UTF 8) and that of my
webhoster (Linux, Apache 2, PHP 5.1.2, default-charset Latin1) -
time_limit, which is set to 30 s seems not to work.
Executing the script via CLI produces the same result (but can be
cancelled by Ctrl-C)
The snipped shall look for adjacent blocks, each persisting of a
separator character followed by one or more characters that aren't
control- or separator-characters.
Crashing is independent of the $aName-value and the result, the match
would produce.
The example is stripped down from a bigger pattern - always having to
kill the webserver after each test is quite annoying :(
Reproduce code:
---------------
<?php
$aName = 'My Name';
preg_match('/^(\\p{Z}[^\\p{C}\\p{Z}]+)*$/', $aName);
?>
Expected result:
----------------
just nothing happens - the function returns and drops its result (false
in this case, but doesn't matter)
Actual result:
--------------
Server "crashes": CPU usage is at 100% and Apache doesn't respond to a
restart (php compiled as module).
