Summary: I suspect you ran out of stack space

Try typing 'limit' to UNIX. It will tell you what your current
program size and stack size limits are. I suspect, that since your
variables are local, and hence placed on the stack, that you have
overflowed the stack size limit.

One can set stacksize limits via:

% limit stacksize  amount

where amount is how much space you want
