I do not have access to https://bugs.webkit.org/show_bug.cgi?id=86534, so I can't comment there. The bots indicate this started somewhere in between r118093 and r118096: http://build.webkit.org/results/Lion%20Debug%20(Tests)/r118093%20(6860)/results.html http://build.webkit.org/results/Lion%20Debug%20(Tests)/r118096%20(6861)/results.html 118095 was rolled out in 118116 and the crash still happens after that, so that leaves http://trac.webkit.org/changeset/118094 http://trac.webkit.org/changeset/118096 Given the backtrace, I think it is http://trac.webkit.org/changeset/118096, since that modified ContainerNodeAlgorithms.h Process: DumpRenderTree [25856] Path: /Volumes/VOLUME/*/DumpRenderTree Identifier: DumpRenderTree Version: ???

Note: I am hesitant to just skip this test because when I run locally, other tests (with no clear pattern) also hit this crash. I am hesitant to roll out the change because it also fixes a crash. Not really sure what to do here re: the tests.

Also note that this is not just affecting WK1. It is causing crashes in WK2 as well: http://build.webkit.org/results/Lion%20Debug%20(WebKit2%20Tests)/r118178%20(7408)/results.html At least two of those crashes (though the links to the crash logs are broken) are this crash.

(In reply to comment #1) > I am hesitant to roll out the change because it also fixes a crash. I'd recommend rolling out r118096 and reopening the bug (assuming that fixes the tests). r118096 fixed an unlikely crash and in exchange caused likely crashes in basic functionality.

I asked the sheriff to roll it out. See https://bugs.webkit.org/show_bug.cgi?id=87285.

So this seems resolved by the rollout. *** This bug has been marked as a duplicate of bug 87285 ***
