--- Comment #17 from Daniel Micay <danielmicay at gmail dot com> --- It's well-defined C code though. It shouldn't be possible to for anything to go wrong here when using -fstack-check, i.e. it should be guaranteed to trigger a stack overflow which is caught. The size wrapping back around is different.
