Sorry, something went wrong.
Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector: - collections.OrderedDict.items - dict.items - enumerate - functools.reduce - itertools.combinations - itertools.combinations_with_replacement - itertools.permutations - itertools.product - itertools.zip_longest - zip Previously, they could have become untracked by a prior garbage collection. (cherry picked from commit 226a012)

CC @pablogsal, just to make sure I'm doing the manual backport with cherry_picker correctly (automatic backporting failed).
