IMO, a well-designed program or library should *never* segfault. If an
external library routine receives incorrect input, the routine should fail
with some sort of helpful error message. If an internal routine receives
bad input, it ought to no-op if it can, or raise an assertion failure if.
that wouldn't work. (Not sure if C has those, though...)
