Valgrind definitely found something kinda directly related to my new code;
still have to understand what goes wrong at the lowermost call though. Some
relevant output:

*==19443== Invalid read of size 8*

Is 0xd8 the address returned by the lowermost call by any chance
(i.e. SdrTextObj::ImpGetDrawOutliner())?
