I am trying to build Python 3.6.1rc1 on Fedora, and have the following test failing on arm64 (aarch64) architecture:

======================================================================
FAIL: test_pass_by_value (ctypes.test.test_structures.StructureTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/builddir/build/BUILD/Python-3.6.1rc1/Lib/ctypes/test/test_structures.py", line 413, in test_pass_by_value
    self.assertEqual(s.first, 0xdeadbeef)
AssertionError: 195948557 != 3735928559
----------------------------------------------------------------------

The build log is attached.
The test was added in this commit [1] as a fix for bpo-29565.

Any idea what this can be related to?
