[Python-modules-team] Bug#893743: python-cffi: FTBFS on hurd-i386: test_thread AssertionError

[Aaron M. Ucko]

Source: python-cffi
Version: 1.11.5-1
Severity: important
Tags: upstream
Justification: fails to build from source (but built successfully in the past)
User: debian-hurd at lists.debian.org
Usertags: hurd

The latest build of python-cffi for hurd-i386 (admittedly not a
release architecture) failed, per the below excerpts from [1]:

Could you please take a look?
