@jkoritzinsky and @jtschuster This seems a bit odd. The generator is deterministic, so why aren't we seeing this more regularly or in the recent CI? Perhaps this is the non-determinism for A/V, but I'm surprised we haven't seen this before.

The unit tests are all managed code I think. Was this something with us, or something with the runtime?

@AaronRobinsonMSFT

Was this something with us, or something with the runtime?

That is the question. My initial guess here would be we are generating something bad.

@jtschuster

Member

Generating something bad shouldn't cause a segfault unless we run the code, right? And I don't think we run generated code in the unit tests.

@AaronRobinsonMSFT

Member

And I don't think we run generated code in the unit tests.

Ah. I thought we run some of that code. Okay.

@jkoritzinsky

Member

Yeah we don't run any generated code in the unit tests. We only generate the code and then use the Roslyn APIs to inspect it. We only run the code in the "integration" tests (ie LibraryImportGenerator.Tests)

I am seeing this failure affecting also ComInterfaceGenerator.Unit.Tests, and in release/8.0. Could it be the same root cause?

Yes, it is possible that this is the same failure.

@agocke The above link is for a failure in System.Numerics.Vectors.Tests. Is this really realted to the LibraryImport source generator?

oh, do those tests not use the generor? OK, this must just be catching extra stuff

Adjusted the error message, hopefully this will catch only LibraryImportGenerator segfaults now

I think it's worth closing this. Whatever was causing the LibraryImportGenerator failures looks more likely to be a runtime instability problem that has been resolved.
