Jean thankfully tested the binaries I produced with that change, and
they don't seem to completely break while fixing the crashes with the
originally reported scores. Note that there are apparently still
crashes with debugging scores that Jean produced, calling (gc) on every
translator slot...

With the fix of the user scores merged though, I've now started to
produce 2.23.13, I'll announce it once ready later today.

What are the updated feelings on the plan of branching next week? If we
agree to stick to that plan, I will bump master to 2.23.80 in
preparation of the first release candidate. If not, I'll go with
2.23.14 with the possibility that this version will never see the light
of the world...
