Well, it just so happened that the first file I tried on Arch makes lilypond dump core, sheer bad luck. As per the suggestion here (which I didn't even think of, too busy rushing into worrying about this) my other files compile fine. So in fact there is no real issue. I'll binary chop the file to see what's going one. I did have my suspicions about the file to begin with, as it had somehow lost more recent changes I thought I had made.
Thanks all for your assistance. This is so great, and I can say after having used pretty much every major linux distro over the decades, that Arch is by far the best of all, for my personal development use anyway! I even have Manjaro running on my Pi 4 and as far as I am concerned it's far and away superior to Debian on the Pi. But I am veering off topic.
