Why do we have to put a pointer to Method into the vtable to be
compatible? Have you considered modifying intrp so it stores a
pointer to the bytecode in the vtable (and allocates the bytecode
so that GC_getObjectBase(address of some bytecode) returns the
address of the Method* the bytecode belongs to)? And what happens
to xdebugging when the vtable doesn't contain a pointer to the
code of the method?
