[New-bugs-announce] [issue33867] Module dicts are wiped on module garbage collection

[natedogith1]

New submission from natedogith1 <natedogith1 at gmail.com>:

When a module is garbage collected, it fills it's __dict__ with None.  issue19255 and issue18214 seem to suggest that this was fixed, along with github pull request 7140 (commit 196b0925ca55bf22ffbb97733cff3e63d4fb6e18).  However, this still seems to be an issue in 2.7.14 and 3.6.2.

>>> import sys
>>> a = type(sys)('a')
>>> b = a.__dict__
>>> b['__name__'] is None
False
>>> del a
>>> b['__name__'] is None
True
