There is a very probable WeakKeyDict bug in Python standard library (to be confirmed and investigated further) that manifests itself in a very rare failure of the test_stacktrace_on_failure_starts_with_task_execute_method This turned out to be related to an unexpected behaviour (and most likely a bug - to be confirmed) of WeakKeyDict when you have potentially two different objects with the same `equals` and `hash` values added to the same WeakKeyDict as keys. More info on similar report (but raised for a bit different reason) bug in Python can be found here: https://bugs.python.org/issue44140 We submitted a PR to fix the problem found python/cpython#31685

Thank you for first pull request. But we need an issue on bugs.python.org unless the pull request don't change any behavior (e.g. fixing typo, code cleanup). But we are planning to moving issue tracker from bugs.python.org to GitHub issues in this month.
This change is not so easy as you think. In Python, True == 1, False == 0, 2.0 == 2. We guaranteed "first wins" semantics for very long time. So it is not an option to change the dict. I recommend you to start discussion in: Both discussion can be used during issue tracker migration. When posting your idea on the discussion, please describe your use case more concretely. |

@malthe Might be worth turning this in to a doc update to mention this "gotcha" for the next people? |

Yep. We already asked for it https://bugs.python.org/issue46925 and Python maintainers agreed it's a good thing to do and reopened the issue to be "doc-issue". |
