If your variables are stack based, you can increase the stack
size using stubedit for your program (usually 512KB, but
can be changed).  If you are allocating your variables via
new, malloc, or static storage, there is no limit (other than
the amount of memory / paging / dpmi memory available).

If increasing the stack size does not resolve your problem,
then it is some other bug, not sizing related.  Look at the
line number referenced by symify for more details.
