[MMTK] Pyrex evaluator backtrace

Hi,

here is the backtrace from running mdtest.py. If I run just test.py  
everything works fine. It's only in MD or minimization runs that the  
evaluator crashes right away.

I have a Linux machine where I did the same tests and they act the  
same as on the Mac. The backtrace is from Linux.
