@radical - has this happened on any other build than your PR? Does it repro in main? If yes - do you have repro steps on what kind of build, and on what platform, this repros on?

radical · 2022-05-20T21:38:26Z

No, I have seen it only this one time.

eerhardt · 2022-05-20T22:08:25Z

No, I have seen it only this one time.

Are you sure the failure isn't caused by your changes? Can you repro it yourself with your changes?

radical · 2022-05-20T22:29:12Z

It passed on the second attempt by azdo for the same commit of my branch. My PR has very few non-wasm specific changes, and this is not for a wasm run.

eerhardt · 2022-05-20T22:32:26Z

Hmm, that's odd for a NRE in the linker to be non-deterministic. @agocke @vitek-karas @sbomer - thoughts?

MichalStrehovsky · 2022-05-23T05:30:05Z

If it's indeed non-deterministic, it's probably an issue in the .NET runtime running the tool.

We started to see various mystery bugs in managed tools that run as part of the build ever since switching to the .NET 7 SDK/runtime.

Here's a similar NRE in crossgen2: #69454. The theory is that these are all related, possibly fixed with #68443 and will be fixed once we update to Preview 5 (#69593 (comment)).

radical · 2022-05-26T00:30:03Z

Another NRE, though it doesn't look the same. But I'll leave it up to others to decide whether to split it off into a new issue or not. This is on p5 rolling build:

Hmm, that method body hasn't been modified recently. It also doesn't look like it happened in the next build. Seems unlikely to be a linker issue.

Do we have a working theory for what is causing these?

The other recent linker exceptions - dotnet/linker#2789 , and #70031 .

eerhardt · 2022-06-03T18:49:18Z

Or a way to get a trace dump so someone can investigate? Has anyone been able to repro this outside of CI?

vitek-karas · 2022-06-03T18:53:42Z

As far as I know we haven't seen this outside of CI - and it's not very common in CI either (less than once a day). The current theory is that it's related to #68443.
For example here is a similar failure in crossgen2 (similar as in relatively random NRE): #69192

Problem is that crossgen2 and linker both run on the runtime which comes with the SDK and not with the runtime which is live built. So even though the possible cause of this has been fixed for a while, it can still show up for the tools.

As for the crash dump - we have discussed this a little, but I'll continue that discussion today. Right now I don't think we have a way to get a crash dump of these failures from the CI. And even locally it will be hard - it's an exception which is handled by the process, so one would have to run it under debugger to catch this.

So to clarify, it looks like we're waiting on #70117 which @ViktorHofer would prefer not to land until p5 is officially released? How much confidence do we have that the fixes in p5 will resolve the issues?

Another one on #20220603.2

This doesnt appear to be the potential GC issue. @radical, Is there a dump available to look at?

I don't see one. Maybe @vitek-karas has an answer (ref: #69536 (comment)).

agocke · 2022-06-07T17:42:55Z

AFAIK this is only happening in builds, and we don't collect crash dumps on build machines. However, we should change the linker to stop swallowing exceptions, dotnet/linker#2824

agocke · 2022-06-17T16:56:55Z

If this was a GC hole, as we suspected, then Preview 5 is merged and this shouldn't happen anymore. Closing until we see new faliures.
