[Bug c++/21312] New: [3.4/4.0/4.1 Regression] Access violation diagnostic given twice

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Like PR 19375, the following code gives the diagnostic twice:
class A {
private:
    int i;
};
class B : public A {
};
class C : public B {
public:
    void f() { A::i = 0; }
};
