Subject: Re: [PHP-DEV] PHP 5.3 bug or changed feature??
From: helly@php.net (Marcus Boerger)

Hello Rob,

  this is intended. The 5.2 solution is just a hack and returns a wrong
result in the first place. The hack was however introduced to make
development easier. Now with 5.3 we were able to change the API and coudl
apply the solution that was first developed in HEAD.
