this is an example from the official C++ Standard which should be used as test
case, "11.2 Accessibility of base classes and base class members":
class B {
public:
int mi; // nonstatic member
static int si; // static member
};
class D : private B {
};
class DD : public D {
void f();
};
void DD::f() {
mi = 3; // error: mi is private in D
si = 3; // error: si is private in D
B b;
b.mi = 3; // OK (b.mi is different from this->mi)
b.si = 3; // OK (b.si is different from this->si)
B::si = 3; // OK
B* bp1 = this; // error: B is a private base class
B* bp2 = (B*)this; // OK with cast
bp2->mi = 3; // OK: access through a pointer to B.
}
If you comment out the erranous lines gcc still complains with:
> error: `class B' is inaccessible
