Alexandre Vassalotti added the comment: It is an integer overflow issue. It is easy to reproduce without numpy:
$ python2.7 -c "import cPickle; cPickle.dumps('\x00' * 2**31)" Traceback (most recent call last): File "<string>", line 1, in <module> SystemError: error return without exception set We fixed this in Python 3. It may be worthwhile to fix cPickle as well. ---------- nosy: +alexandre.vassalotti stage: -> needs patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11872> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
