I'm not able to repro this locally. Maybe we should wait until another run or two verifies that it continues to fail.
BruceForstall commentedon Jun 30, 2023
Well, a separate PR run still failed with these, so these failures look repeatable.

@stephentoub Is #87906 possibly related? It's the only recent change I found with "Event" in the title.
@noahfalk @davmason Any idea what might have changed here?
stephentoub commentedon Jun 30, 2023
Anything's possible, but this seems very unlikely. It just replaced one singleton instance with another and shouldn't be anywhere near to code that impacts whether something has an extra null terminator.
davmason commentedon Jun 30, 2023
I am not aware of any changes here. I merged #86850 last night, but it looks like it was merged after this started failing so wouldn't be the issue. Other than that I don't know of any recent changes

This fails consistently in runtime-extra-platforms too: https://runfo.azurewebsites.net/search/tests/?q=started%3A%7E7+definition%3Aruntime-extra-platforms+name%3ASystem.Diagnostics.Tests.EventLogMessagesTests.CanReadAndWriteMessages
So doesn't seem like a jitstress issue. Given that it fails in jitminopts, it's also very unlikely to be a JIT issue., so will move this out.

The failure appears to only be on Windows 11. I've disabled it there in #88472.
