I was unable to get it to reproduce again on ubuntu, I suspect I was just SSH'd
into the wrong machine or something. Sorry for wasting your time on that.
After debugging the issue, it appears to be the same as
https://sourceforge.net/p/testlilyissues/issues/4814/
I've submitted a patch to NixOS to build stable lilypond with
-fno-delete-null-pointer which appears to fix the issue.
Thanks,
Jason
