[issue24667] OrderedDict.popitem()/__str__() raises KeyError

[Eric Snow]

Eric Snow added the comment:

As expected (considering the link to dict ordering here), the inconsistent results are tied to hash randomization:

$ for i in `seq 1 25`; do echo $i; PYTHONHASHSEED=$i ./python /tmp/odict_reproduce.py; done
