----------------
With multiple inheritance this offset won't make sense, and it gets 
particularly fun with diamond virtual inheritance. This is a minefield.

And what about non-standard layout classes in general, like the simple ones 
that just have a vtable, not just ones that have virtual inheritance somwhere?
