[issue1621] Do not assume signed integer overflow behavior

Martin Panter added the comment: Perhaps we should add a test for the __length_hint__() overflow to tuple_and_list.patch: >>> a = [1,2,3,4] >>> import sys >>> class B: ... def __iter__(s): return s ... def __next__(s): raise StopIteration() ... def __length_hint__(s): return sys.maxsize ...

[issue27581] Fix overflow check in PySequence_Tuple

Martin Panter added the comment: Hmm maybe this patch is okay. We are assuming size_t will fit more than PY_SSIZE_T_MAX. The alternatives I can think of would be equally ugly: /* Risks loss of precision, e.g. 64 bit integer from floating point */ if (n < (Py_ssize_t)(PY_SSIZE_T_MAX / 1.25) - 1
