--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. What is interesting is if we don't use -pedantic-errors, the
following is accepted:
```
template <class T, T a, T b>
class A;
template <auto n>
class A<decltype(n), n, n> {};
A<int, 1, 1> b;
```
And even more if we have 2 different values for the 2/3rd arguments, it is
rejected as an incomplete class.
