Re: Lilypond 2.19.83

[Jean Abou Samra]

These mis-predicted force programming errors look like this issue:

https://sourceforge.net/p/testlilyissues/issues/4975/

The ticket only mentions this problem appearing on Windows but I had also encountered it on Mac OS starting from LilyPond 2.21.0 (pre-release) but not 2.19.83, which is exactly your case. I had been able to reproduce the bug on the two examples given on the ticket and on a third one of my own, a very simple MWE which I reported to -users-fr. Unfortunately, I’m on my webmail right now and I can’t find it again. Could someone on the French list forward it here? The subject was ´mis-predicted force’. Thanks.

So, as a recap, Michael, your issue is entirely different from the original one. It is an instance of issue #4975, a platform-specific bug introduced between LilyPond 2.19.83 and a recent master, occurring on Windows and Mac OS X but not GNU/Linux so far. It seems to happen on code involving grace notes and it produces a lot of ´mis-predicted force’ programming errors.

Jean Abou Samra.
