Comment 2 ayumi_kojima 2021-07-30 16:39:47 PDT

I was not able to reproduce the crash on iOS 15 simulator on my local machine using: 

run-webkit-tests --iterations 500 --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2 --ios-simulator http/tests/resourceLoadStatistics/ping-to-prevalent-resource.html

Comment 3 ayumi_kojima 2021-10-15 11:06:26 PDT

I was not able to reproduce the failure locally on iOS 1 simulator using run-webkit-tests --ios-simulator --debug --force --iterations 500 --exit-after-n-crashes-or-timeouts 1 http/tests/resourceLoadStatistics/ping-to-prevalent-resource.html
