Description from bug 38502, which was split in 2 separate issues: r58712 made fast/workers/worker-gc2.html crash. I played a lot with this bug. If I skipped fast/workers/worker-gc2.html, fast/workers/worker-gc.html crashed. And I had a suspicion, I thought it is a DRT sideeffect. After skipped the test before fast/workers/worker-gc.html, I didn't get any crash. (with run-webkit-tests fast/workers --iterations 100) So I skipped fast/workers/worker-event-listener.html until fix: http://trac.webkit.org/changeset/58746
This test is no longer on skipped list. It passes: http://build.webkit.org/builders/Qt%20Linux%20Release/builds/38749/steps/layout-test/logs/stdio
