I also hit this in an unrelated PR: #81070 The shared failure message seems to be:
It's affecting at least 3 Generator Roslyn tests:
Microsoft.Extensions.Logging.Generators.Roslyn3.11.TestsCallstack
System.Text.Json.SourceGeneration.Roslyn4.4.TestsCallstack

native crash on mono/linux/arm64
This issue has heavy impact in many PRs. Looking for an area owner. |
This seems to happen in different suites, so disabling may turn into a whack-a-mole game. For example, I spotted one happening in System.Security.Cryptography tests. |
going to try to decode the crashed ip address in-process in the crash handler. #83219 |
I can reproduce a crash on osx with the Microsoft.Extensions.Logging.Abstractions/tests/Microsoft.Extensions.Logging.Generators.Tests/Microsoft.Extensions.Logging.Generators.Roslyn4.0.Tests.csproj |
Some of the failures appear to be races with delegate invocation.
This fails when ran in a loop on on an apple m1. |
So the problem seems to be related to the invoke trampolines which do: These trampolines are stored into delegate->invoke_impl by mono_delegate_trampoline (). Another thread makes an indirect call through delegate->invoke_impl and observes delegate->method_ptr being NULL. delegate->method_ptr is also set by mono_delegate_trampoline (), but even with a memory barrier between the stores, its not guaranteed that another thread will not observed the previous NULL value. |
We think The numbers on March 21 2023 before the change were:

Thanks @lambdageek and @vargaz. Once we confirm that fixes the issue, please consider backporting it to 7.0. We are seeing the failure happen there too. [Pending verifying benchmark results as @lambdageek told me offline]. |
#83688 is probably needed too. |

Most of the recent hits are either on the 7.0 branch, or are unrelated false positives (the query catches too many other native crashes) There is one hit from #84004 from System.Security.Cryptography.Tests.WorkItemExecution that seems real:

It still seems to crash, but the crashes are less frequent. |
The XML test lately failing are showing something like:
