New submission from Hirokazu Yamamoto <[EMAIL PROTECTED]>:
Following code crashes. (See issue4170)
trunk/Modules/cPickle.c (save() or save_reduce()) needs more checks of
returned value from __reduce__.
class C(object):
def __reduce__(self):
return C, (), None, None, [] # 5th item is not an iterator
class D(object):
def __reduce__(self):
return D, (), None, [], None # 4th item is not an iterator
import sys
if sys.version_info[0] == 3:
import pickle
else:
import cPickle as pickle
pickle.dumps(C()) # crash
pickle.dumps(D()) # crash
