I'll try and get a test case done over the weekend..
should be quite simple - create a overloaded object (with __call) - and
assign some vars's then set it so something else.. (based on a rough
guess)..
The real code is a bit to complex for a simple test case - but it broke
both my devel servers. ;)

Can you provide some example of the code that crashes? Of course I'd
prefer the code that I could run, so that I can check what's the
problem.
Removing unlock won't do good - it would just cause a memory leak.

Actually both changes in this commit cause big problems with overloaded
objects
http://cvs.php.net/diff.php/Zend/Attic/zend_execute.c?sa=1&r1=1.316.2.41&r2=1.316.2.42&ty=u
removing 1st fixes crashes
removing 2nd fixes object properties getting destroyed/lost? when
calling methods of overloaded objects.
