The bug demo can be reduced a little further:

class A
{
protected:
  int x;
};

class AA:public A
{
public:
  using A::x;
};

class foo:public A // <<-- foo is the culprit!
{
  friend class T;
};

class T
{
public:
  AA aa;
  void foo(){aa.x=0;}
};

int main()
{
}

Same behavior and conditions for the error as before.
