You clipped the context enough that I'm not quite sure what you mean by
"it", but from the subject I'll assume "it" is a stack overflow. In
which case functional programming is actually _less_ likely to require a
huge stack if you have tail recursion and know how to use it. Also, most
functional languages, in my experience, don't use a statically-allocated
stack for subroutine call returns.

A stack overflow is not a bus error. It's a segment violation. And quite
often, a stack overflow _is_ a program error.
