>>> import sys
>>> xrange(0, sys.maxint, sys.maxint-1)
xrange(0, -4, 9223372036854775806)
See also issue #16029. There should be a common solution to both these issues. Suggestion is to write a 'range_safe_stop' utility function that returns r->start + r->len * r->step clipped to the range [LONG_MIN, LONG_MAX], and use that for the stop value in both the repr and the pickle.
