--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note it is the decltype for the trailing return type that is causing the issue.
That is this works just fine:
```
template <int...>
void Foo() {};
template<typename ...T>
void Foo3(T... is) {
return (decltype(Foo<is...>()))0;
};
void f()
{
Foo3();
}
```
