Is your function taking huge stack parameters or is it recursive? It seems
unlikely that a "normal" non-recursive function with a few int and pointer
parameters would overflow the stack, although the nature of the crash
indicates it.

If you are working with objects, it might be some copy constructor, which is
invoked when it is passed to the function, that freaks out. The environment
can be pretty different when running as CGI.

Anyhow, try finding out how much stack space your process/thread have, and
compare the shell and CGI cases. Again, I don't remember how to get that
