On a lark, I decided to try running the regression tests with -r, which tells regrtest.py to run the tests in random order. With this, I get the following warnings from test_long.py:

../Lib/test/test_long.py:266: OverflowWarning: integer addition special = [0, 1, 2, 3, sys.maxint-1, sys.maxint, sys.maxint+1] ../Lib/test/test_long.py:287: OverflowWarning: integer addition got = x + y ../Lib/test/test_long.py:291: OverflowWarning: integer subtraction got = x - y ../Lib/test/test_long.py:295: OverflowWarning: integer multiplication got = x * y ../Lib/test/test_long.py:313: OverflowWarning: integer exponentiation got = x ** y ../Lib/test/test_long.py:320: OverflowWarning: integer exponentiation got = pow(x, y, z) ../Lib/test/test_long.py:377: OverflowWarning: integer exponentiation value = 10 ** exp

This was with the CVS trunk, which is still virtually identical to the 2.2c1 release. I won't have time to look at them this weekend, but this should be fixed. It may be possible there are other order-dependent behaviors, so it would be really good if people who have time can run the tests with -r on whatever platforms are available and report any other anomolies.
