But here is a legitimate question, how do we get the interfaces?
There's
no indication in the ABI of where the interfaces are. I know from logic
that they must be before the data members. But logic also says that
interfaces defined by the derived types must appear after the data
members
of the base class. This is indeed tricky.
I'd guess that the interface vtbls are referenced from the class vtbl,
so clearing the vptr should wipe everything.
They aren't. They must occupy a pointer in the class, or else interfaces
would have to be fat pointers (vtbl + this ptr)
