Serhiy Storchaka added the comment: In very rare circumstances it is possible that after a series of modifications using raw dict methods, ma_keys becomes to point to the same address, but allocated keys array has different size. But the guard in _odict_get_index uses only the address as resize sentinel. This can cause segmentation error if found key index is larger than the size of od_fast_nodes. Following patch adds the value of keys->dk_size as a sentinel.
