--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Slight more reduced:
```


template <class _Tp>
struct s1 {
      static _Tp* _S_fun(_Tp& __r) noexcept;

      static void _S_fun(_Tp&&) = delete;
      template<typename _Up, typename  = decltype(s1::_S_fun(_Up{}))> 
      s1(_Up&&);
};


using my_func = void(int) &&;
s1<my_func> b;
```
