--- Comment #3 from Patrick Palka <ppalka at gcc dot gnu.org> ---
template<typename T>
class MyClass {
  private:
    static constexpr bool cond =3D true;
  public:
    MyClass(T) requires cond;
};

MyClass c{0};


The problem seems to be that the access context during satisfaction of #1's
implicit guide [with T=3Dint] is MyClass<T> instead of MyClass<int>, and
MyClass<int>::cond (the substituted result of maybe_dependent_member_ref) is
considered inaccessible from MyClass<T>.=
