I'm very talented in finding unusual problems for almost every piece
of software I'm using :-)

Lilypond definitely needs to protect against this. I suggest to
either add an iteration counter somewhere or to estimate the number of
iterations (per line? per page? whatever) in advance in case this is
possible. Then LilyPond could provide one or more configuration
values to limit the number of iterations.
