--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Actually A at that point is incomplete type.
Note MSVC gives really bad diagnostic for:
```
struct A{
int x;
static constexpr const A a{1};
};
```
says undefined type A rather than incomplete type.
Anyways GCC's check for incomplete type happens before the other checks.
Plus GCC allows it with -fpermissive ....
