(I'll look at the source code later). I remember investigating it while on =E2=80=98core-updates-frozen=E2=80=99= =E2=80=A6 and eventually forgetting about it. :-/ I think the pragmatic approach in such situations is to: 1. Report the test failure upstream, including the test log; 2. Skip tests (ideally selectively) for i686-linux, adding a link to the upstream bug report. That makes sure we move forward while not just sweeping issues under the carpet. Ludo=E2=80=99.
