Interesting. Do the attributes apply to derived classes automatically?
struct B __attribute__((reorder)) {
char a;
int b;
};
struct D : public B {
char c, d, e;
};
Is D also allowed to reorder members a and b? even with an explicit
__attribute__((reorder))?
Would this break static_cast-ing from D to B due to change in layout?
D d;
int x = static_cast<const B&>(d).b; // how does this work if D's layout is not
a mere extension?
This might warrant a diagnostic saying this might not do what is expected.
(What DOES one expect?)
