           Summary: Protected friend function in parent class will not
                    compile
           Product: clang
           Version: 3.4
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal

Steps to Reproduce:
Compile the following code:

    class A {
    protected:
        void ProtectedMemberFunc() {}
    };

    class B : public A {

    };

Expected result:
The code compiles without error.

Actual result:
The following error is raised:

main.cpp:8:20: error: friend function 'ProtectedMemberFunc' is a protected
member of 'A'
    friend void A::ProtectedMemberFunc();
                ~~~^
main.cpp:8:20: note: must name member using the type of the current context 'B'
