[New-bugs-announce] [issue39689] test_struct failure on s390x Fedora Clang buildbot

[Charalampos Stratakis]

New submission from Charalampos Stratakis <cstratak at redhat.com>:

The clang build was recently added for that buildbot and it seems on that particular architecture, test_struct fails with:

======================================================================
FAIL: test_bool (test.test_struct.StructTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/dje/cpython-buildarea/3.x.edelsohn-fedora-rawhide-z.clang-ubsan/build/Lib/test/test_struct.py", line 520, in test_bool
    self.assertTrue(struct.unpack('>?', c)[0])
AssertionError: False is not true

https://buildbot.python.org/all/#/builders/488/builds/6

Fedora rawhide recently upgraded Clang to version 10. The rest of the architectures seem fine.
