I tried cherry-picking this patch at some point, but hit some difficult test failures and haven't had time to follow up on it: https://github.com/python/cpython/pull/296 According to FRidh from NixOS in that thread, this fix is also needed: https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/interpreters/python/cpython/3.6/default.nix#L75 Help in this area very welcome! > I can’t find Debian’s patches in > <https://alioth.debian.org/scm/loggerhead/pkg-python/python3-defaults-debian/files/head:/debian/>, > but they probably have something.
