New submission from Walter Prins:
It appears that Windows 8 (Version 6.2.9200 x64) has introduced changes in
behaviour that causes the multiprocessing module's use of overlapped
PipeConnection to fail (Python 3.4 32bit and release 3.3.2 32bit).
This issue previously existed (see issue #12328 point 1) and was fixed but the
fixes for #12328 do not appear to work on Windows 8.
Specifically the test test_multiprocessing._TestPoll.test_empty_string fails
with message:
FAIL: test_empty_string (Lib.test.test_multiprocessing.WithProcessesTestPoll)
----------------------------------------------------------------------
Traceback (most recent call last):
File
"C:\Users\Walter\Documents\src\cpython\Lib\test\test_multiprocessing.py", line
2416, in test_empty_string
self.assertEqual(a.poll(), True)
AssertionError: False != True
Additionally, there appears to be no buildbot for Windows 8 currently, would it
be possible to have one set up?
