It would be useful to find a repro case for this I think.

I was able to reproduce the crash on Big Sur arm64 (Remote machine) using: run-webkit-tests --iterations 100 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 http/tests/workers/worker-importScripts-banned-mimetype.html --debug However, no crash log was obtained with this crash.
