The GC uses counters and thresholds to decide which collection and when they should be collected. I tried to play with gc.set_threshold(), but I failed to reproduce the issue on Linux. Maybe it's a very precise threshold which triggers the issue. Between Linux and macOS, the site module executes different code paths which produce different GC counters. Sometimes, the GC must happen in a very precise line, one line later is too late. See bpo-44422 for a case of threading.enumerate() (different kind of bug, but it's related to the GC). See bpo-44184 for another example of GC bug which only occurred on Windows and only if you type an exact command line. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44895> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
