Well the current Squeak.make does -O2, so I tried it with -O3 and at 
least the jitter 3 one promptly crashs. So I tried -O2 -funroll-loops 
this works slightly better. I'd suggest you try -O3 & loop unrolling 
with Apple's gcc and see if it works

The current CW built VM is compiled with loop unrolling. This makes 
some difference since it produces quite different code for GC work, 
(movement of object in new space) and for object creation (zeroing 
out the block). These two actions rate very high on the things that 
are run.
