An acciaccatura is giving 14 "programming error: mis-predicted force" errors and corrupt layout. The former I can live with the latter I can't.

I've tried to produce an MWE, and one is appended, but it doesn't show the layout errors which for me are a complete show-stopper. It's a slightly out of date version of LilyPond
I see "mis-predicted force" with 2.19.80 and 2.19.83 but not with 2.19.84 or 2.20.0 Cheers, Robin
