On AIX, with commit 4fb15021890d327023aefd95f5a84ac33b037d19 (HEAD -> master, origin/master, origin/HEAD)

test_thread is failing.

The three sub_tests that exit as ERROR are:
ERROR: test_threads_join_2 (test.test_threading.SubinterpThreadingTests)
ERROR: test_frame_tstate_tracing (test.test_threading.ThreadTests)

These two have in common:
Traceback (most recent call last):
ImportError:    0509-130 Symbol resolution failed for /home/buildbot/python-master/build/lib.aix-7.1-3.8-pydebug/ because:
        0509-136   Symbol _PyMem_GetAllocatorsName (number 191) is not exported from
                   dependent module python.
        0509-192 Examine .loader section symbols with the
                 'dump -Tv' command.

FAIL: test_daemon_threads_fatal_error (test.test_threading.SubinterpThreadingTests)

I am guessing that:

FAIL: test_daemon_threads_fatal_error (test.test_threading.SubinterpThreadingTests)
Traceback (most recent call last):
  File "/home/buildbot/python-master/Lib/test/", line 942, in test_daemon_threads_fatal_error
    self.assertIn("Fatal Python error: Py_EndInterpreter: "
AssertionError: 'Fatal Python error: Py_EndInterpreter: not the last thread' not found in 'Traceback (most recent call last):\n  File "<string>", line 2, in <module>\nImportError: \t0509-130 Symbol resolution failed for /home/buildbot/python-master/build/lib.aix-7.1-3.8-pydebug/ because:\n\t0509-136   Symbol _PyMem_GetAllocatorsName (number 191) is not exported from\n\t\t   dependent module python.\n\t0509-192 Examine .loader section symbols with the\n\t\t \'dump -Tv\' command.'

is caused by the earlier failures.

That's the bug bpo-36402 which I fixed with commit 468e5fec8a2f534f1685d59da3ca4fad425c38dd in master.
