Summary

0001714: preg_grep("//", NULL) throws unexpected NullPointerException

Description

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

preg_grep("//", NULL) throws unexpected NullPointerException.
The behavior differs from the php 5.1.6 behavior which just returns NULL.
The problems makes impossible using dokuwiki-2006-11-06 (dokuwiki.org) over Resin.

Notes
(0001866) salishev 04-27-07 08:25	The problem is the () inside character class [] means not the capturing group but a pair of bracket chars.

(0001867) salishev 04-27-07 08:30	The problem is a regression from resin-3.1.s070319
