I'm having a problem allocating a larger stack than the default.  I've
got a large program, approximately 330 K for the .EXE file.  When I
increase the stack size from 2K to 8K with the EXEMOD utility, the
program immediately exits with a stack overflow error (R6000).  Running
the program with a smaller stack results in a stack overflow error later
on.  I've tried using overlays, but this doesn't seem to make any
difference.

Anyone have any ideas on what do here?  There's not much more code that
I can hack away and I'm not going to be able to use extended memory.
Thanks in advance.

Have you tried using a /stack:8192 linker option? This will at least
tell you at link time whether the 8K stack is too big.  If it is,
you'll have to make room for it by moving some data items out of the
default data segment into a separate data segment (using the 'far'
keyword).

Enjoy,
