Comment 2 Hercules Hjalmarsson 2022-07-15 11:13:00 PDT 
I was able to reproduce this issue on iOS15 wk2 Release arm64 ToT running 1k iterations of command:

run-webkit-tests -f --force js/dom/Promise-reject-large-string.html
Comment 3 Hercules Hjalmarsson 2022-07-15 11:29:23 PDT 
The failure rate of this test is ~99% which makes it almost a constant failure on ToT.
