Created attachment 363659 [details] Command List The following layout tests are Crashing on iOS editing/selection/thai-word-at-document-end.html fast/events/clipboard-event-constructor.html fast/events/focusingUnloadedFrame.html fast/shadow-dom/click-text-inside-linked-slot.html http/tests/cache/cache-control-immutable-http.html quicklook/numbers-09.html fast/events/beforeunload-alert.html Probable cause: These seven tests began crashing somewhere between 242401-242405. Each of these tests by themselves does not usually crash but crashes consistently when run alongside a test blamed in their crash logs. I am attaching a file with each of the commands for reproducing each tests crash. I am able to reproduce these currently on 242405 and all tests pass on 242401. Results: https://build.webkit.org/results/Apple%20iOS%2012%20Simulator%20Release%20WK2%20(Tests)/r242464%20(2967)/results.html
