I suppose this is referring to
? It's always helpful to link to explicit messages, lilypond-user sees
far too much traffic for me to keep fully up with it and topics are
sometimes discussed in (somewhat) unrelated threads due to when they
come up...

I personally think this should not block the release, simply because
big scores have been a pain point on Windows before due to 32-bit
limitations [1]. It would of course be nice to fix it (and _maybe_ we
can patch in only the minimal parts of the patch), but otherwise I
think it is fine to release with a "known issue" as suggested by Karlin
(though that issue and the accompanying note in the release
announcement need to be very user-friendly).


1: I'm actually surprised that 2.22.1 can go to 625 scores in the
message I linked above, for 2.23.14 already 400-ish scores use more
memory than a 32-bit process could have used. I'll need to check
