Reproduced the failure at BigSur Debug ToT x86_64 using the following test: run-webkit-test imported/w3c/web-platform-tests/webaudio/the-audio-api/the-analysernode-interface/realtimeanalyser-fft-scaling.html --iterations 1000 -f Failures happen most commonly on Apple Silicon Macs in Debug, but it has a fairly long history of occurring in Intel Catalina and BigSur in release and debug.
