--- Comment #6 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Relatedly, decltype(V) where V is an NTTP can also incorrectly return a
reference type:
template<auto V, class T = decltype(V)>
struct A { using type = T; };
constexpr int N = 42;
template<class T>
constexpr const int& f(T) { return N; }
template<class T>
using AT = A<f(T())>;
using type = int;
using type = typename AT<int>::type; // bogus error: const int& != int
