[Python-Dev] More joy with test_strptime

[Tim Peters]

Today (CVS HEAD), test_strptime is failing on WinXP, in release and debug
test runs, but only when I run the full test suite:

test test_strptime failed -- Traceback (most recent call last):
  File "C:\Code\python\lib\test\test_strptime.py", line 289, in
test_bad_timezone
    self.failUnlessEqual(tz_value, -1)
AssertionError: 0 != -1


If I run it in isolation, it does not fail:

OK

The regrtest framework alone is not making it fail either:

C:\Code\python\PCbuild>python ../lib/test/regrtest.py test_strptime
test_strptime
1 test OK.

Best guess is that some earlier test (in a full test run) is screwing up
locale in a way test_strptime can't recover from.  Maybe that's enough so
that you know who you are <wink>.
