Hmm. No, agreed, not ready for release yet. This one prevents me using
Lilypond on Windows for anything other than pathologically small projects
(i.e. nothing that's actually useful).

https://sourceforge.net/p/testlilyissues/issues/4943/

We've traced the symptom of the crash down to Assertions being raised since
some point in 2.19, but AFAIK the cause is still unknown.

I've tried to create a symbols build so we can trace back / debug, but Gub
is simply not working for me. I don't really have the time to investigate
the Lilypond bug (which I have motivation to do), so I really don't have
time to investigate why Gub isn't working (which I really don't have
motivation for).

I've given up trying to make an instrumented build of Lilypond for
Windows/Mingw now, so if anybody else is able to create one for me that'd
be very welcome.
