Summary

0002943: preg_replace doesn't deal properly with empty subexpression

Description

<?php
$foo = "12345xy6789";
print preg_replace('/^(|[^x]*x)y.*/', '\1', $foo);

Vanilla PHP prints "12345x". Quercus prints "12345xy6789" -- the empty alternative at the beginning of the subexpression confuses it. If you remove the "|" this test works (but that obviously changes the meaning of the regular expression.)
