State-Changed-Why:
    not a bug. your code is ill-formed.
    you are attempting to delete a derived object using a
    pointer to one of its bases. Refer to [5.3.5].
    In particular, if the static type of the object (base in
    your case) is different to the dynamic type (derived),
    the static type shall be a base of the dynamic type (ok),
    and the static type shall have a virtual destructor, otherwise
    the behaviour is undefined.
