in the provided folder run $ dub test --force to see a bunch of undefined reference when linking. Worked until 2.088.1.
Created attachment 1766 [details] zipped folder to run the command in
Works fine for me with beta2. Makes sense, as there's no more core.thread.Thread, the class has been moved to core.thread.osthread.Thread, so you're most likely just having an issue with stale objects, or a dub issue, if `--force` isn't working.
Or maybe you just extracted the new DMD archive into an existing directory, so that old imports (core/thread.d) mess up things.
yeah it was almost that. I usually install using rpm directly so old sources were still in usr/include/dmd
