Bug Description

https://launchpad.net/ubuntu/+source/libffi/3.1~rc1-2 has a regression which causes lots of crashes on i386. This particular crash report is a (local) retrace of https://jenkins.qa.ubuntu.com/job/trusty-adt-gtk-3.0/109/ARCH=i386,label=adt/ but this affects all reverse depdencies of libffi, such as

  https://jenkins.qa.ubuntu.com/job/trusty-adt-python-cffi/37/ARCH=i386,label=adt
  https://jenkins.qa.ubuntu.com/job/trusty-adt-gtk-3.0/109/ARCH=i386,label=adt/
  https://jenkins.qa.ubuntu.com/job/trusty-adt-ruby-ffi/26/ARCH=i386,label=adt/

and gvfs, umockdev, ubiquity, etc.

I reproduced this in a local trusty i386 schroot and confirm that downgrading libffi6 to the previous version 3.0.13-12 re-fixes things.

So far a small reproducer is:

sudo apt-get install python3-gi gir1.2-gtk-3.0 xvfb
xvfb-run python3 -c 'from gi.repository import GLib, Gtk; GLib.timeout_add_seconds(1, Gtk.main_quit, None); Gtk.main()'

Or you run python-cffi's test suite:

python3 -m pytest -v -k test_callback_as_function_argument testing
