I see, I would have never suspected the camera within a large number of
non-hollow objects being the cause.

Yes, well actually "200 frame level", as the stats tell it, and "100
infinite".  So I gather it's the infinite that are non-hollow objects.
Since one less loop and it's fine.  Non-hollow, infinite.. makes sense to
me.

Luckily that particular method wasn't needed, the non-error way works fine.
I only stumbled upon the wrong way while trying to get there.

Empty and Hollow section is there, just haven't seen any mention of a
limitation for how many there can be.
Very grateful to you for solving this question Thorsten.   Not a bug is the
prognosis, I can live with that.
