--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So if we have (note the extra f which has no arguments):
```
template <int N> struct A { alignas (N) int a; };
template <int N> struct B { char c; };
template <int N> int f (int (*)[sizeof (A<N>)]) { return 0; }
template <int N> int f (int (*)[sizeof (B<N>)]) { return 1; }
template <int N> int f () { return 2; }
int i = f<3>();
```
This started to get accepted in GCC 12.
