--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
C++ says it is undefined at the point of fall through point. THIS is different
from C where it is undefined if the value was used.
AND yes this was done on purpose. If you want to catch it at runtime you could
use -fsanitize=undefined.
