privbug.cc:6: the method void A::foo (int) is private
privbug.cc:17: within this context
Looks like a bug to me. I tried various things, not too carefully.
It doesn't happen if D inherits directly from A. I can work around it
by specifying A::foo(4) explicitly. It seems like it is getting
confused about protected and public methods.
