--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The specialization which works for both GCC and clang
```
template<>
template<>
struct A<B>::AA<int> {
..
};
```

So note clang should have rejected the specialization in comment #0 too; see PR
39906 and bug 69903.


So this moving this bug report to be about the incorrect diagnostic of the
invalid specialization . So confirmed.
