Modern IDB: Some IDB tests crash in ~SQLiteIDBBackingStore https://build.webkit.org/results/Apple%20El%20Capitan%20Debug%20WK1%20(Tests)/r195523%20(2419)/results.html https://build.webkit.org/results/Apple%20El%20Capitan%20Release%20WK1%20(Tests)/r195522%20(2803)/results.html https://build.webkit.org/results/Apple%20El%20Capitan%20Release%20WK1%20(Tests)/r195523%20(2804)/results.html Haven't seen these locally, but the crash logs all suggest the same thing: Crash tearing down the JSGlobalObject in the backing store constructor. The JSGlobalObject almost certainly needs to be cleared out before the VM, instead of vice versa.
Cannot get to this in a timely manner tonight with only my laptop and the sad state my build is in. Will get to it first thing in the morning.
This was almost certainly introduced along with the VM in http://trac.webkit.org/changeset/195517 I'll land a speculative fix before going to bed.
Unreviewed speculative fix landed in http://trac.webkit.org/changeset/195525 Will check the bots in the A.M.
At least one test was reliably crashing before the speculative fix, and it hasn't happened since. Closing.
