This is probably related to https://trac.webkit.org/changeset/269774/webkit
Comment 5 Truitt Savell 2020-11-16 13:51:07 PST
I can reproduce these crashes with command:
run-webkit-tests --iterations 2000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 10 --debug-rwt-logging --no-retry --force --no-build -f fast/lists/001-vertical.html fast/lists/001.html
