I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

@adamsitnik would you be able to tell if it is problem with perf infra, or with the specific benchmark?
Any idea where to route it?

[adamsitnik]

@karelz these particular benchmarks are used as unit tests (not to measure perf). Based on:

      Got a SIGSEGV while executing native code. This usually indicates
      a fatal error in the mono runtime or one of the native libraries 
      used by your application.

I think it's Mono Runtime bug.

[naricc]

This looks like it must be a race condition somewhere in the mono runtime. I am trying to reproduce it locally now.

[naricc]

I haven't yet been able to reproduce this locally, so I think it is probably something that only happens infrequently, and apparently only one linux-arm64? I don't think its a blocker for .net7 and am putting it in the .net8 milestone.

@karelz - do we have more recent failures to review the logs ?

@jandupej - please follow up. Thanks

[karelz]

No idea, I don't monitor the runs anymore. I would recommend to check out Kusto for recent failures and check their logs.

[SamMonoRT]

Closing this issue. Should re-open if there are still failures.
