Hi Mike,

The answer to your problem is in section 15.9 of the FAQ. It says that
the default stack size is 256k, "but some programs which use large
automatic arrays ... might need more." One of the suggestions it gives
is to use STUBEDIT to increase the stack size. So I tried giving your
test program a 1Mbyte stack and it worked fine. Good Luck.

Chris
