It may be interesting to add the compiler version to test.pythoninfo. It would be simpler to compare Windows buildbots to identify a bug. Currently, the only info is: "sys.version: 3.7.0a4+ (heads/master:9d411c1, Jan 23 2018, 15:13:42) [MSC v.1900 32 bit (Intel)]" Some environment variables are also dumped: os.environ[VS100COMNTOOLS]: C:\Program Files\Microsoft Visual Studio 10.0\Common7\Tools\ os.environ[VS140COMNTOOLS]: D:\Program Files\Microsoft Visual Studio 14.0\Common7\Tools\ os.environ[VS90COMNTOOLS]: D:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\ In the compile step, I see lines like: "Microsoft (R) Build Engine version 14.0.24730.2" I recall also issues with outdated ucrtbase DLLs. Maybe we can also dump the version of such DLL? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32641> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
