No, but it's not surprising: Guile sometimes seems to be a one-person hobby project.

One of the great things about Linux - and a major contributor to its success - is its golden rule of never knowingly breaking anything (in userspace). If it works today it has to work tomorrow. You aren't allowed to break it, *even* if you're fixing something more important. I wish more projects were like it (especially where I work). To practically answer your question: I don't think there's much we can do: we are more or less at the mercy of the Guile project. I'm tempted to suggest we add some tests that might catch breaking changes to Guile's GC, but of course our most recent issues were on Windows only, so our automated testing wouldn't have caught them anyway. Perhaps we could describe some manual tests that get run on new releases of Guile? (It's probably less work than rewriting LilyPond from scratch with a different embedded language :D.)
