tracing/eventpipe/eventsourceerror/eventsourceerror test always failing locally on Linux / macOS

[janvorli]

This test always fails in my local coreclr test runs on Linux and macOS:

  1.9s: SentinelEventSource:0xFFFFFFFFFFFFFFFF:5,
  1.9s: ]
  1.9s: }

  1.9s: Expected:
  1.9s: {
  1.9s: "IllegalTypesEventSource" = 1 +- 0
  1.9s: }

  1.9s: Actual:
  1.9s: {
  1.9s: "IllegalTypesEventSource" = 2
  1.9s: "Microsoft-DotNETCore-EventPipe" = 1
  1.9s: "Microsoft-Windows-DotNETRuntimeRundown" = 3628
  1.9s: "Microsoft-Windows-DotNETRuntime" = 4
  1.9s: }
  1.9s: ==TEST FINISHED: FAILED!==

It seems that similar to #47625, the Microsoft-Windows-DotNETRuntime* events are not expected by the test

Interesting. As far as I'm aware, this isn't failing in CI or PR validation.

@janvorli did this start recently or has this been ongoing?

[janvorli]

@josalem this has been failing like this for quite some time, I don't know when it started, but it has been at least a month, maybe more.

And it is failing on all of my machines, including the new mac M1 in both Rosetta 2 and arm64 mode.
