What did you do?

Ran go list -e '-json=GoFiles,CgoFiles,HFiles,CFiles,CXXFiles,SFiles,EmbedFiles' -tags custom_tag

This is a flaky issue, rerun helps. However it's happening regularly.

What did you expect to see?

Normal json output

Thanks for the report. For this to be actionable we'll need some way to reproduce the problem -- could you please share which go repo or package you are running this on. You mention that this problem is intermittent/flaky, does it happen on other machines?

podtserkovskiy commented 2 weeks ago

could you please share which go repo or package you are running this on.

Unfortunately I can't share a specific example at the moment, because this code is not open sourced.

You mention that this problem is intermittent/flaky, does it happen on other machines?

Yes, I've seen it on several different machines.

I can keep looking into our build logs to find a pattern and create some example.

Repro code: https://github.com/podtserkovskiy/repro-golang-go-issue-67113 Repro command: 

CGO_ENABLED=0 GO111MODULE=off GOARCH=amd64 GOEXPERIMENT=nocoverageredesign GOOS=darwin go list -e '-json=GoFiles,CgoFiles,HFiles,CFiles,CXXFiles,SFiles,EmbedFiles,CgoCFLAGS,CgoCPPFLAGS' -tags .

I guess this may be kind of a race condition issue, but it seems like src/make.bash doesn't offer an option to build go command with -race.
