The code:
struct base {
protected:
    virtual void foo() {}
    };

struct der : public base {
    virtual void foo() { p->foo(); }
    base* p;
    };

gets you:
~/ootbc/sim/test$ g++ foo.cc
foo.cc: In member function 'virtual void der::foo()':
foo.cc:3: error: 'virtual void base::foo()' is protected
foo.cc:7: error: within this context

------- Comment #1 from pinskia at gcc dot gnu dot org  2007-04-03 04:36 -------
This is not a bug. You are allowed to call protected functions on this but
nobody elses.

This has nothing to do with derived class or not.  This is just how C++ works.
