AFAICT, the attachment includes everything needed in a bug report. Inlining the
code here for convenience:

#include <utility>

template <typename T, int N>
auto a = (struct A {
    template <class T1, int>
    using Temp = T1;

    template <int... I>
    auto get(std::index_sequence<I...>){
        return (int (*)( Temp<T,N>... ))nullptr;
    }
}){}.get(std::make_index_sequence<N>{});

int main () {
    a<int, 4>;
}
