[Bug c++/7302] -Wnon-virtual-dtor should't complain of protected dtor
------- Comment #15 from ben at decadent dot org dot uk 2007-02-22 01:10 -------
Pawel: Yes, any friend class or function can call a protected or private
destructor wrongly. So can members of the class - in fact, even pure virtual
members can, since they may still have definitions!
The current implementation warns whenever any function might be able to call a
non-virtual destructor in a polymorphic class; this results in many false
positives. False warnings result in programmers disabling the warning, or
paying less attention to warnings, or (in this case) introducing a virtual
destructor for no good reason. That is why I consider the behaviour a bug.
