This may be an unintended fallout of !8940. Would you try starting an<br>
i386 pipeline with it reversed to see if it solves the issue, in which<br>
case we should revert or fix it in master?<br>

When I checked just now, there were 8 nightly runs still running. :) Thus I'm going to cancel the still-running nightly-i386-linux-deb9-validate jobs and let the pipelines die in peace. You can still find all examples of failed jobs on the dashboard:<br>
