I came across a situation where LilyPond crashes caused by a badly placed \pageBreak. I've chopped most of the music out of the example but when I tried to remove more the crash stopped. The error message ends:Finding the ideal number of pages... Fitting music on 1 page...lilypond: /home/gub/NewGub/gub/target/linux-64/src/lilypond-git.sv.gnu.org--lilypond.git-stable-2.22/lily/page-breaking.cc:1073: void Page_breaking::line_divisions_rec(vsize, const Line_division&, const Line_division&, Page_breaking::Line_division*): Assertion `my_index == 0' failed.
