Paul Moore added the comment: Nothing obvious or Windows-specific from what I can see. It does seem to me that EnvironmentVarGuard doesn't monkeypatch os.environ even though it looks like it intends to (__exit__ sets it back, but __enter__ doesn't monkeypatch it). So maybe that's doing something weird?
I'll try to have a better look later (not much spare time right now). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20053> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
