Summary

0001717: Unexpected ArrayIndexOutOfBoundsException in preg_split

Description

I've checked with latest available resin-3.1.s070425 snapshot

preg_split throws unexpected ArrayIndexOutOfBoundsException.
The behavior differs from the php 5.1.6 behavior.
The problems makes impossible using dokuwiki-2006-11-06 (dokuwiki.org) over Resin.
