--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced a little further:
```
template<int D> struct blurb 
{ constexpr static int d=D; };

template<int> struct pant{};

template<typename Base>
struct bug : Base
{
    using Base::d;
    struct problem : pant<d> {  };
};

template struct bug< blurb<2> >;
```
