Raymond Hettinger added the comment:
I would think that the PY_SSIZE_T_MAX check belongs inside the:
if (result != NULL) {
it->it_index++;
return result;
}
just before the increment which could cause the overflow. Also, PY_SSIZE_T_MAX
is a valid value to pass to PySequence_GetItem(), so it shouldn't be blocked
unless necessary.
