There are lots of situations where this assertion may trigger and not all of them may have a sensible fallback. So one would need to see what particular case is triggered here. -- David Kastrup _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond
