printing/print-close-crash.html has started crashing on debug testers, once in 5-10 runs on average.
The first crash was on r160493:r160529 range, which makes me strongly suspect <http://trac.webkit.org/changeset/160515>.
Unfortunately, I can't reproduce this locally. Perhaps this only happens when accessibility is enabled by an earlier test, and this state is leaked into this printing test?
One way to test would be to run the accessibility tests first
./Tools/Scripts/run-webkit-tests accessibility printing
which would leave on AX during the printing tests.
I'll also give it a try
Great idea, I could reproduce with:
./Tools/Scripts/run-webkit-tests accessibility printing --child-processes=1 --batch-size=100000 -2 —debug
Chris suggested r160515 to be rolled out for now. I also filed bug 126021 to track the general case, as we do the same thing in many places.
I confirmed that undoing r160515 makes the issue no longer occur for me locally.
Landed the rollout in <http://trac.webkit.org/r160866>.
