--- Comment #5 from Patrick Palka <ppalka at gcc dot gnu.org> ---
A reduced valid C++11 testcase:
template <int...> struct integral_constant {
static const int value = 1;
};
template <class... T> using mp_all = integral_constant<T::value...>;
template <class... T> using check2 = mp_all<mp_all<T...,
integral_constant<0>>>;
check2<> x;
We started ICEing on this one after r6-1487.
