The patch for issue #16029 fixes this issue, too.

[issue16030] xrange repr broken for large arguments

2012-09-24 Thread Mark Dickinson 

New submission from Mark Dickinson:

Python 2.7.3+ (2.7:f51d11405f1d+, Sep 24 2012, 21:39:19) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type help, copyright, credits or license for more information.
 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.
