Does it incorrect from standard standpoint:

class A { int member; };

class B : A { public: using A::member; };

If it is allowed why so many compilers having issues with it?

I don't see why you think it should be allowed. A::member is private, not protected. It's not accessible from B.

Sorry I meant protected of course. class A { protected; int member; }; class B : A { public: using A::member; }; Gennadiy
