Comment 2 Robert Jenner 2022-12-06 16:33:44 PST

The regression point is very clear in the history link. It appears that 256538@main cause this API-test to fail. 

I have also reproduced the failure at macOS Ventura Debug ToT running the test as follows:


run-api-tests TestWebKitAPI.IPCTestingAPI.SerializedTypeInfo

And I also confirmed that 256538@main introduced the failure, with the failure occurring when testing 256538@main, but not at 256537@main.
