<pre>Per <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#472">http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#472</a> we should
not allow the following code:
class B {
public:
int m;
};
class S: private B {
friend class N;
};
class N: private S {
void f() {
B* p = this; // OK because class S satisfies the fourth condition
// above: B is a base class of N accessible in f()
because
// B is an accessible base class of S and S is an
accessible
// base class of N.
}
};
class N2: protected B { };
class P2: public N2 {
void f2(N2* n2p) {
B* bp = n2p; // error: invented member would be protected and naming
// class N2 not the same as or derived from the
referencing
// class P2
n2p->m = 0; // error (cf 11.4 [class.protected]) for the same
reason
}
};
GCC correctly raises a diagnostic.</pre>
