I didn't know about the second one - thanks.
As for the first, COM doesn't allow virtual destructors in interfaces, which are just abstract base classes like IA. Making the destructor virtual in A won't help if there isn't a slot for it in IA's vtable. And it doesn't need to be virtual since it is only called from the virtual release method.
