I was able to reproduce this bug on macOS Ventura using arm64 running the test as follows:

run-webkit-tests fast/media/managed-media-source-open-crash.html --iterations 50

Using the flakiness dashboard, I was able to identify that the regression point appears to be the test's introduction to the project at 264554@main.

Comment 5 Ben Schwartz 2023-07-25 10:22:04 PDT
To clarify, this is a flaky failure; however, it is fairly consistently failing (which is why I wrote "consistent/flaky failure" in the original bug message).

I have marked this test as a flaky failure while this issue is investigated (https://github.com/WebKit/WebKit/pull/16070).
Comment 6 Ben Schwartz 2023-07-27 09:41:56 PDT
Investigation completed, determined that it is normal for the test to either pass or fail. Closing as resolved.
