How much memory do you have?  One change in 1.12 is that, by default, gcc
and make do not page everything out when spawning if less than 1MB (?) of
extended memory is used.  Have you tried using stubedit to set keepmem to 0
for the crashing programs?  This doesn't apply under dpmi, which may be why
you don't see the same problem under Windows.

I've malloc'ed several MB with a single call.  I might not have done more
than 100's of KB with 1.12 though.
