Barry A. Warsaw <ba...@python.org> added the comment: Pure chance I believe. It all depends on the MAC address of the machines the test runs on (which is perhaps an unacceptable environmental variability in the test suite, and should be fixed/mocked?).
FWIW, I saw the failures on my 2017 MacBook Pro, where the MAC address did have that bit set on two of its interfaces. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32107> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
