I'd been seeing two problems with 3.5.5-1 in OCaml repeatably failing:
- mingw-w64 gcc 12.4.0-1 failing at
https://ci.appveyor.com/project/dra27/ocaml/builds/51332994?fullLog=true
and https://ci.appveyor.com/project/dra27/ocaml/builds/51333141?fullLog=true
- gcc 12.4.0-3 failing at
https://github.com/dra27/ocaml/actions/runs/12796669773/job/35676846151?pr=180
- gcc 12.4.0-3 failing at
https://github.com/dra27/ocaml/actions/runs/12796669773/job/35676845712?pr=180

I had tried this on 8 Jan, and they were still failing with the 19 Dec
3.6.0 snapshot, but I'm afraid I hadn't had a chance to turn them into
any kind of helpful report (in particular, I hadn't managed to
reproduce the mingw-w64 outside of CI).

However, I tried 3.6.0-0.320.g1e6a3b39f1c6 in
https://github.com/dra27/ocaml/pull/180 and both those issues appear
to be resolved, thank you! (the test which is still failing is not to
do with Cygwin!)

> I want to take the opportunity to emphasize that in general cygwin is very stable and such issues are rare

I'd like to echo this as well. Also, since setup acquired the ability
to specify versions, and the older releases hang around for a while,
when these things do happen it's trivial to put CI workarounds like
https://github.com/ocaml/ocaml/pull/13718 in place. Thanks for the
work you all do on Cygwin!

All best,


David
