This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

This is fixed in PHP-5.0.0-dev and can not be backported to PHP 4.3.3-dev due to limitations in the engine.

There maybe a solution for this bug for 4.X, however it needs testing. Once it has been validated or rejected final decision about the status of this bug will be made.
