State-Changed-Why:
    Not a bug.  The virtual function is treated as non-virtual
    inside destructors.  So ~A() can only call A::f() which is
    pure virtual.  Here is the relevant part of the standard
    [section 12.7 para 3]
    ... When a virtual function is called directly or indirectly
    from a constructor (including from the mem-initializer for a
    data member) or from a destructor, and the object to which
    the call applies is the object under construction or destruction,
    the function called is the one defined in the constructor or
    destructor's own class or in one of its base, but not a function
    overriding it in a class derived from the constructor or
    destructor's class, or overriding it in one of the other
    base classes of the most derived object (1.8).
