[New-bugs-announce] [issue15354] _PyObject_LengthHint only accepts longs

[Philip Jenvey]

New submission from Philip Jenvey <pjenvey at underboss.org>:

The __length_hint__ optimization was broken a while ago for many iterators due to a bug introduced in 44c090c74202. It only accepts longs as valid hints, not ints

This affects 2.6 too (but that's in security-only fix mode), but not 3.x
