--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For the non-static case, "default member initializer" applies.

That is:
```
#include <cstddef>
struct A {
    char a;
    static constexpr int off_p = offsetof(A, a);
};
```

is illformed too.

But
```
#include <cstddef>
struct A {
    char a;
    int off_p = offsetof(A, a);
};
```
is well formed due to it being a DMI.
