Description:
------------
I've been trying to fix this for a loong time now. Unfortunately, I am not able to reproduce this error with using a mass amount of classes or a large PHP application so I can't submit 10-20 lines of reproduce code.

I've tried this with multiple version of PHP including 5.0.4, CVS, and 5.1/

Here's the backtrace:
