I presume you threw something in BAR? If not, your code does not
correspond to your question and your object is not guaranteed to be
destroyed if I remember correctly. std::terminate will be called and
clean-up is implementation defined.
Bu otherwise: Yes - of course! If your compiler does forget the clean-
up you are not using your compiler in a compliant way.
