When access such members in client code, the compiler reports: 'Base' is an inaccessible base of 'Heir' >How-To-Repeat: class A { public: int i; }; class B {}; class D : A { public: using A::i; }; class E : A, B { public: using A::i; }; int main() { D d; d.i; E e; e.i; // "`A' is an inaccessible base of `E'" } >Fix: None. Change private inheritance to public inheritance can work, but it breaks the semantic. >Release-Note: >Audit-Trail: >Unformatted:
