--- Comment #3 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Works with -fstack-reuse=3Dnone. Somehow GCC is confused about stack layout=
 in
func_36. It leaves rsp misaligned by 8 mod 16, but computes the base of l_8=
14
for
__builtin_memset (&l_814, 0, 80) as if rsp is aligned mod 16.=
