--- Comment #2 from Robert Jenner <jenner at apple.com> ---
I have marked an expectation for this test here:
https://commits.webkit.org/265340@main

I was also able to reproduce the crash at iOS 16 Debug ToT running the test as follows:

Run-webkit-tests --iOS-simulator imported/w3c/web-platform-tests/webcodecs/videoFrame-construction.crossOriginSource.sub.html

I verified that the same crash is seen on Intel Mac Debug, and iOS Debug. I have also bisected to a specific regression point. 265142 at main appears to have broken this test, causing it to crash. 

I set my checkout to 265141 at main, and re-ran the test at the same iOS16 Debug ToT build and the crash did not reproduce. I then updated the checkout to 265142 at main, and re-ran the test again and the crashing returned.
