Mac OS X Version - Nov 2002 - "Illegal instructions"

Hi!
Without any special options, hugs crashes on me when performing certain 
list operations.
I assume this has to do with a memory management issue, but that's just 
a wild guess.

The exact value seems to depend on the heapsize.
I have downloaded the binary distribution from haskell.org and use it 
on Mac OS 10.2.2
I will provide further information if you need it.
