Original bug report at https://bugzilla.redhat.com/show_bug.cgi?id=1174037
Additional informations at Issue bpo-20160
Note that this was reproduced not only with separate libffi package but also with libffi bundled in python.
Reproduced with Python 2.7.9 but same issue should exists also in 3.4.x.
Richard Henderson provided fix in original bug report at bugzilla (attached).

Consider to apply a patch or update bundled libffi.

Does this version include libffi-henderson patch?
rkuska commentedon Feb 9, 2015
Sorry for the late answer, I forgot about this issue.
3.2.1 doesn't contain required fix(sorry for the misleading suggestion 'or update bundled libffi' from report) but master branch at upstream repo (https://github.com/atgreen/libffi) does.
iritkatriel commentedon Sep 9, 2021
I believe we are on libffi 3.3 now - the code on that branch looks very different from this patch. Can we close this issue?
vstinner commentedon Sep 9, 2021
The bug was reported on Fedora (Linux).
We do now have a multiple AArch64 buildbots running Fedora and the whole test suite now pass there.
Example with "aarch64 Fedora Stable 3.x":
https://buildbot.python.org/all/#/builders/125/builds/612
"0:00:03 load avg: 4.20 [ 62/427] test_ctypes passed"
So yes, this issue can now be fixed ;-)
FYI Python is built with --with-system-ffi on Fedora, but buildbots don't use this flag. I'm working on using --with-system-ffi on buildbots, see:
python/buildmaster-config#264
