The reason I suggested getting the C backtrace was to see if it
was failing in the GC or elsewhere. Failing in the GC could be caused
by many things as the GC does not react well to a corrupt heap. 

I've seen Squeak lock up consuming 100% CPU due to the 2 Gig memory
problem due to using ints rather than unsigned ints for address
calculation. 

It would be helpful if you could find out if your problem is related
to that, or something new.
