Additional note: I just tried to narrow down the error cause, only to find
deliberate code changes to affect the outcome in the weirdest of ways. I did
find that disabling a certain statistics counter would prevent the segfault;
but when examining *why* that was the case, and trying mark pixels on screen
for which a certain safety check would fail, I found that I could turn the
segfault on or off by nothing more than changing the "marker color".

To cut a long story short: This looks like a typical "wild pointer" to me, so
the underlying error could be *anywhere* in the code.

As balcony.pov is the only of the sample scenes where I have been getting
segfaults on a regular basis, I currently presume it has something to do with
media or photons. But even that is just a wild guess.
