[Bug 1620754] Re: hash(datetime.datetime(...)) fails with python3.5 on armhf (on an arm64 host) with a bus error

[Martin Pitt]

Hello Matthias, or anyone else affected,

Accepted python3.5 into xenial-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/python3.5/3.5.2-2~16.04 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  seen with
  https://launchpad.net/ubuntu/+source/python-cryptography/1.4-2/+build/10476934
  https://launchpad.net/ubuntu/+source/python-cryptography/1.5-1/+build/10678695

  the TestInvalidityDate.test_invalid_invalidity_date test is the first
  one to fail with a bus error. No reasonable traceback from gdb.

  Trying to build python3.5, python-cffi and python-cryptography with
  -mno-unaligned-access doesn't fix the issue (buildds running on a
  64bit kernel).
