[issue12596] cPickle - stored data differ for same dictionary

[Ramchandra Apte]

Ramchandra Apte added the comment:

Try `./python -R -c "import pickle; print(pickle.dumps({'a':1, 'v':1}))" |md5sum`. The output will differ on subsequent run, while trying `./python -R -c "import pickle; print(pickle.dumps({'a':1}))" |md5sum`, the output is always the same. I suspect because the order of dicts are different on every run (try repr).
