Ignore the history link above. I accidentally pasted the wrong on in. Here is the correct history link: https://results.webkit.org/?suite=layout-tests&test=inspector%2Funit-tests%2Fheap-snapshot-collection-event.html

I have reproduced the failure at BigSur Production ToT using the following test: run-webkit-tests inspector/unit-tests/heap-snapshot-collection-event.html --iterations 100 -f It failed all 100 times when running that test. The history shows a clear regression point of r277437, and I was able to confirm it. The above test passes at r277436, but fails at r277437.
