Please try using this CVS snapshot:

For Windows:

Confirming latest snapshot fixes this error.

Unfortunately this snapshot seems to make all classes passed by value rather than by reference like they were in php4.

Edit: Discard; patching process created conflict in local paths and selected an INI that had the wrong php4 compatability set.
