  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).
