New submission from Kevin Shweh <[email protected]>:
The OrderedDict iterator caches a di_result tuple for use with
iter(od.items()). It's *supposed* to only do that for the items() case, but the
code does
if (kind & (_odict_ITER_KEYS | _odict_ITER_VALUES))
to test for this case. This is the wrong test. It should be
if ((kind & _odict_ITER_KEYS) && (kind &_odict_ITER_VALUES))
The current test allocates di_result for key and value iterators as well as
items iterators.
