        <pre>When given the following code, clang generates an error and proposes a fix to
the given error :
   
-----------------------------------------------------------------------------------------
    class parent { protected:
    virtual void foo() = 0;
    };

    template<typename T> class child : public parent {
    void (parent::*foo_ptr)() = &foo;
    };

   
-----------------------------------------------------------------------------------------
    $ clang private.cpp -std=c++11 
    private.cpp:7:30: error: must explicitly qualify name of member function
when taking its address
            void (parent::*foo_ptr)() = &foo;
                                        ^~~~
                                         parent::
    1 error generated.


Updating the code according to the error message still fails :

   
-----------------------------------------------------------------------------------------
    class parent { protected:
    virtual void foo() = 0;
    };

    template<typename T> class child : public parent {
    void (parent::*foo_ptr)() = &parent::foo;
    };

   
-----------------------------------------------------------------------------------------
    $ clang private.cpp -std=c++11 
    private.cpp:6:39: error: 'foo' is a protected member of 'parent'
            void (parent::*foo_ptr)() = &parent::foo;
                                             ^

context 'child<T>'
            virtual void foo() = 0;
                         ^
    1 error generated.

The error messages should be consistent and propose fixes that will not
generate more errors.</pre>
