[New-bugs-announce] [issue7657] test_ctypes failure on AIX 5.3

[sangamesh]

New submission from sangamesh <swamy.sangamesh at gmail.com>:

I built the python-2.6.2 with the latest libffi-3.0.9 in AIX 5.3 using xlc compiler.
When i try to run the ctypes test cases, two failures are seen in test_bitfields.

test_ints (ctypes.test.test_bitfields.C_Test) ... FAIL
test_shorts (ctypes.test.test_bitfields.C_Test) ... FAIL

It seems that interpreting type c_int and c_short is wrong in bit field for AIX. If i change the type c_int and c_short 
to c_unit and c_ushort of class "BITS(Structure)" in file test_bitfields.py then no failures are seen and all the test 
cases got passed

This issue is common for both 32 and 64-bit versions

Attaching the complete test case result for reference.
