Some debugging happening at https://github.com/ruby/date/pull/125 already! Should this be moved to the date repo, by the way?

We need to backport fix if the problem is our side. This ticket is reminder for that.

The root cause is that the extension is compiled against a newer version of libwinpthread-1.dll and headers from msys2, but at the runtime ruby always load $rubyPrefix\bin\ruby_builtin_dlls\libwinpthread-1.dll which is an older version.
I don't think there is much we can do here.
As for ruby/setup-ruby, our plan is to downgrade msys2's libwinpthread-1.dll for all old rubies that bundle the old version of it, so that the compile time version and runtime version would be compatible.
