note that the EBO is performed again if Derived::a is not the first member,
because then it has a distinct address anyway:

struct Derived : public Base {
    bool b;
    Base a;
};

static_assert(sizeof(Derived) == 2, "empty base");

Closing as invalid, MSVC is wrong to allow two objects of the same type to have
the same address.
