--- Comment #5 from Patrick Palka <ppalka at gcc dot gnu.org> ---
The ICE-on-valid started with r12-2233-gb9119edc09e466, but before that this
was wrong-code:

bool called;
struct foo{
  foo(const int *new_mac) { called =3D true; }
};

typedef int t[1];
int main() {
  foo f((int*)t{ 0xFC});
  if (!called) __builtin_abort();
}

If we do copy initialization instead of direct initialization then we ICE e=
ver
since the sanity check assert was added in r6-6795-g0fd9d4921f7ba2=
