A pointer to the virtual base class subojbect[s] is usually stored
in the class (just like a pointer to the virtual function table),

There are at least two different solutions: CFront stored a
pointer to the virtual base in the class, but other
implementations put the information necessary to do the fix-up
in the vtable. It's also possible to use thunks to do any
fixing up needed; these would also be in the vtable.

Beyond that, there are a number of variations possible in the
details, and as you said, the only way to find out is to ask in
a forum dedicated to the compiler in question, or to look it up
in the compiler's documentation.
