[Bug c++/41796] New: Extended sizeof (referring to non-static member) rises ambiguity

["schaub-johannes at web dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The following code fails for GCC:

struct A { int a; }; 
struct B : A {}; 
struct C : A {}; 
struct D : B, C { }; 
int main() { (void) sizeof(D::a); }

According to the current draft, such use is correct: Name lookup will resolve
to a single declaration, and sizeof does not make additional constraint with
regard to the subobject to refer to. It is reasonable to suspect a standard
defect - this bug report is supposed to be a reminder in that case.
