Oh that makes sense; I was taking a look to see if it was a failure due my changes, but all jobs were marked as cancelled.

It's a bit odd but I think that one is legitimate. I think MSVC failed there with 127, which may mean that there's something Windows-specific about the failure.

I spent some time debugging this issue and it's indeed legitimate. The root cause of the failure in MSVC is the lack of unwind info, which as far as I understand is required in Windows; I can reproduce the exact same failure by disabling the unwind info generation in Cranelift. I'm working on a separate PR to add support for emitting unwind info in Winch.

Ah that sounds familiar! If you want to add #[cfg_attr(windows, ignore)] now for those tests with a comment I think that'd be sufficient.

Sounds good, yeah, I'll ignore them to land this PR and put them back when introducing support for the emitting unwind info.
