--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note you don't need the extra template int argument either to reproduce the
failure:
```
template <typename X> struct Bar {
void accept(X value) { }
};
template <typename...> struct Foo;
template <typename... Ts>
struct Foo<Bar<Ts>...> : Bar<Ts>... {
template <typename T, template <typename> class B = ::Bar>
constexpr static Bar<T>* slice_by_type(B<T>* self) {
return self;
}
template <typename... Us>
void accept(Us... values) {
(slice_by_type<Us>(this)->accept(values), ...);
}
};
int main() {
Foo<Bar<float>, Bar<int>> foo;
foo.accept(3.14f, 10);
}
```
