Indeed. Therefore I want to adapt the rtl at the earliest point possible
where a pointer to object is available to mark for finalization.
It seems this is in Tobject.InitInstance. But afaik this will work with
the code provided. See example.
For AnsiStrings it seems sufficient to take into account the extra
ptrint that registers the size of an entity.
