I can reproduce it on Python 3.5 with attached script.
I think this bug is from Python 3.3, since key-sharing dict is implemented.

"Trigger key sharing dict resize while callbacks (weakref or __del__) called from setitem" is step to reproduce.
It's not easy to exploit because external input (JSON, form, etc) doesn't use key-sharing dict.

Should I fix it for 3.3~ (security fix only) or 3.5~ (bugfix)?
