FWIW, I suspect you were seeing the g++13 issue with -ffast-math 
discussed here:

http://news.povray.org/povray.unix/thread/%3C66d79724%40news.povray.org%3E/

I got very similar symptoms to yours on the update to the g++13 compiler.

Configuring with -fno-finite-math-only fixed the 'bounding not working' 
issue for me (Ubuntu 24.04).
