Hi, this is a "known" problem that I already encountered some time ago: https://gitlab.com/lilypond/lilypond/-/issues/6203 I thought this only affects Ghostscript 9.55 (where you observed the crash) and that 9.54 would be fine (as we use in the binaries with Guile 2.2), so thanks a lot for reporting that the problem is actually much worse. I'll make sure this is addressed before the next release. Jonas
