Comment (by toby_toby_toby@…):

 Switched to base hooks with tags, because fixing of member hook
 failed:[[BR]]

 1) offsetof's approach not working - access violation, null can't be
 dereferenced[[BR]]

 2) fake object "char temp[sizeof(Parent)]" also not working - it actually
 accesses vptr[[BR]]

 3) inspection of additional integers in caster gave nothing - they are the
 same for both cases, no way to deduce
