[adonovan]

Possibly a symptom of #70492?

[matloob]

The error is from running go list -f "{{context.GOARCH}} {{context.Compiler}}" -- unsafe, rather than getting the release tags, right?

[matloob]

The confusing thing here is that it looks like the go command exited 0? I wonder how that could happen?
