Comment 2 Bri Harris 2023-01-26 18:09:56 PST 
I was able to reproduce this failure on Ventura Debug ToT running the test as follows:

run-api-tests TestWebKitAPI.IPCTestingAPI.SerializedTypeInfo

I was also able to bisect and discovered the regression point. It fails at 259112@main but passes at 259111@main.
