--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I particularly like that you can do this and it compiles and runs OK:
assert(test() == 1); // works, unless optimisations enabled
static_assert(test() == 0);
Or to make it always run OK:
#ifdef __OPTIMIZE__
assert(test() == 0);
#else
assert(test() == 1);
#endif
static_assert(test() == 0);
