Comment 2 Ryan Haddad 2023-10-24 16:50:14 PDT

The linked crash log is for a different (non WebGPU) test that isn't indicative of the problem.

Looking through the various crashlogs in https://build.webkit.org/results/Apple-Sonoma-Debug-AppleSilicon-WK2-Tests/269687@main%20(285)/results.html for the WebGPU tests, it looks like there are many different crashes. 

Of the three I randomly picked, one is an assertion failure in WGSL::TypeChecker::visitVariable, another in WebGPU::Texture::aspectSpecificFormat, and another is crashing beneath WebKit.
