New submission from Michael Felt: I am preparing a system with gcc to see if it is compiler related, i.e., goes away with gcc. On the one hand, fingers crossed - but on the other, having bitfields working regardless of the compiler should be preferred.
This issue is similar to a Solaris (C compiler) http://bugs.python.org/issue16275 During the build using clc _ get these messages - which make me hope it is an unexpected compiler issue.

Note: I modified test_bitfields to do an additional print. Maybe this gives an idea about what the issue is (when considering the compiler messages) root@x064:[/data/prj/aixtools/python/python-2.7.12.1/Lib/ctypes/test]../../../python ./runtests.py A 0x1001f 0 B 0x2001d 0 C 0x3001a 0 D 0x40016 0 E 0x50011 0 F 0x6000b 0 G 0x70004 0 H 0x80018 4 I 0x9000f 4 M 0x1000e 6 N 0x2000c 6 O 0x30009 6 P 0x40005 6 Q 0x50000 6 R 0x6000a 8 S 0x70003 8 .............s....................ssss............................ssssssssssssssssssssssssssss...s.......s.....................sssssssssssssssssssss......s...........s....s.....................FF...s...............................................s.............sssss.ss....s.......ss..sss...................s......s.....................s..................................................s...........ss.sssss................s.s.............s. ====================================================================== FAIL: test_ints (ctypes.test.test_bitfields.C_Test) ---------------------------------------------------------------------- Traceback (most recent call last): File "/data/prj/aixtools/python/python-2.7.12.1/Lib/ctypes/test/test_bitfields.py", line 41, in test_ints self.assertEqual((name, i, getattr(b, name)), (name, i, func(byref(b), name))) AssertionError: Tuples differ: ('A', 1, -1) != ('A', 1, 1) First differing element 2: -1 1 - ('A', 1, -1) ? - + ('A', 1, 1) ====================================================================== FAIL: test_shorts (ctypes.test.test_bitfields.C_Test) ---------------------------------------------------------------------- Traceback (most recent call last): File "/data/prj/aixtools/python/python-2.7.12.1/Lib/ctypes/test/test_bitfields.py", line 48, in test_shorts self.assertEqual((name, i, getattr(b, name)), (name, i, func(byref(b), name))) AssertionError: Tuples differ: ('M', 1, -1) != ('M', 1, 1) First differing element 2: -1 1 - ('M', 1, -1) ? - + ('M', 1, 1) ---------------------------------------------------------------------- Ran 440 tests in 0.883s (0 modules skipped) Unavailable resources: printing, refcount FAILED (failures=2) root@x064:[/data/prj/aixtools/python/python-2.7.12.1/Lib/ctypes/test] ---------- messages: 271555 nosy: Michael.Felt priority: normal severity: normal status: open title: test_ctypes fails on AIX with xlc versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27643> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
