Affected EWS Queue: https://ews-build.webkit.org/#/builders/51 First occurrence appears to be here: https://ews-build.webkit.org/#/builders/51/builds/12203 Most recent occurrence was here: https://ews-build.webkit.org/#/builders/51/builds/12322 There is no crashlog produced with any of these reported crashes on EWS, the results just simply indicate that the test crashes. Also, because this test only crashes on EWS, and not on any other platforms, I cannot reproduce the crash anywhere. 1755260 1 jenner 2021-04-28 17:45:34 -0700 Updated test expectations to Pass Crash here: https://trac.webkit.org/changeset/276743/webkit 1755265 2 jenner 2021-04-28 17:58:43 -0700 Test was first found flakey here: https://ews-build.webkit.org/#/builders/51/builds/11834 1755266 3 webkit-bug-importer 2021-04-28 17:59:08 -0700 <rdar://problem/77295341> 1755517 4 ap 2021-04-29 13:40:48 -0700 Not a real crash: 11:04:05.584 68569 com.apple.WebKit.WebContent.Development crash, pid = 75091 11:04:05.747 68569 This test marked as a crash because of no data while reading stdout for the server process. 11:04:05.747 68569 This test marked as a crash because of no data while reading stdout for the server process. 1755518 5 ap 2021-04-29 13:42:10 -0700 (and there is not crash log in ~/Library/Logs/DiagnosticReports around this time)
