--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It does:
itest.c:5:25: runtime error: signed integer overflow: 65536 * 65536 cannot be
represented in type 'int'
itest.c:5:14: runtime error: signed integer overflow: 1679617 * -239945 cannot
be represented in type 'int'
(this is without the #include <stdio.h> and __builtin_printf instead of printf,
but that should make no difference).
Get this both with trunk and -fsanitize=undefined -O3, -fsanitize=undefined
-O0,
and with 7.2.1 with the same option sets.
