Doesn't honor vtable locations? Are you talking about trying to cast an
interface to a class reference, or an interface to a derived interface?
Since that's the only scenario I can think of where the resulting reference
would have invalid vtbl locations. If you're casting from a base *class* to
a derived *class*, there is no way AFAIK that it could end up with invalid
