[issue28427] WeakValueDictionary next bug (with multithreading)

[Larry Hastings]

Larry Hastings added the comment:

I tested this in a freshly-built 3.4.6.  Although it reproduced the behavior you're complaining about--it threw the assert in Armin's test.py, and Serhiy's issue28427.py prints an admonishing FAIL--neither test *crashes* CPython.  So I'm not convinced either of these is a *security* risk.  This is a bug, and 3.4 isn't open for bugfixes, so I don't plan to accept a backport for this in 3.4.

If this is a crashing bug, please tell me how to reproduce the crashing bug with 3.4.6.
