G++ incorrectly rejects the following valid code

struct A { int x; };
struct B { int x; };
struct C : virtual A, virtual B { int x; };
struct D : virtual A, virtual B, virtual C { };

int main()
{
   D* d = new D();
   d->x = 42;
}

Maybe this is not obvious to me why this is valid code, why is this valid code?

paragrpah 10.2/2 from the C++ standard.

d->x should resolve unambiously to d->C::x, because C::x hides
A::x and B::x.
