> Even if I don't see any refleak, you might just run "./python -m test -R 3:3 test_pickle" just to be sure :-)

Change 94d630a02a81 introduced a crash in test_pickle:

Fatal Python error: ..\Modules\_pickle.c:5847 object at 000002B7F7BED2F8 has negative ref count -1

Seen on buildbots, but can always be reproduce on Linux as well.

It seems like you was biten by the surprising _Pickle_FastCall() API which decreases the reference counter of its second parameter. Don't ask me why it does that :-) (I don't know.)

I fixed the bug in the change 328147c0edc3 to repair buildbots.
