@ViktorHofer - hmm, I am somewhat confused, I may be blind but I only see one failure in some iOS Mono run in that AzDO pipeline run, can it be the case that you accidentally shared the link to the wrong run?

I retried the build in that PR. Click on "Show previous attempts" under "Attempt 2".

This is not actionable without a dump.

the log says "core dumped" but I have no idea where that dump would be found.

I think the problem is that this looks like a failure of the .NET CLI itself, the XUnit wrapper build as such seemingly finished fine. I'm not sure whether the test infra caters for this eventuality, probably not. In fact I think this is the first time I'm seeing this type of crash.

Right, this is crash of .NET CLI itself. These crashed are relatively rare, but they do happen.

kernel.core_pattern kernel config controls where the dump is stored.

OK, I guess in such case the actionable aspect of this issue is to make sure we collect dumps from .NET CLI crashes and I'm going to rebrand it like that if you don't object.

Just spoke with MattGal about this and unfortunately we didn't get the dump as it wasn't uploaded. Dump collection unfortunately doesn't work in containers during building.
