cmd/vet: TestVet fails with the latest tip version

[YoshikiShibata]

What version of Go are you using (go version)?

$ go version
go version devel +d1338ec30e Mon Aug 5 19:01:06 2019 +0000 darwin/amd64

Does this issue reproduce with the latest release?

N/A

What operating system and processor architecture are you using (go env)?

What did you do?

I tried to rebuild the latest tip version with all.bash

What did you expect to see?

All tests passed

What did you see instead?

[ianlancetaylor]

I'm not seeing any failures on https://build/golang.org. I can't reproduce the problem myself; for me "all.bash" completes without error, as does go test cmd/vet.

Tell us more about your environment. Are you sure you don't have any local changes?

[YoshikiShibata]

I deleted the local repository and cloned it gain. And then try all.bash:
