--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase to show it is not an issue with decltype:

template <class T>
struct tag_t {
        template <class Sig>
        static constexpr const Sig* smbr = nullptr; 
};

template <class T>
inline constexpr tag_t<T> tag {};
template<class T>
void f()
{
  auto t = tag<int>.smbr<void>;
}
