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

$ go version
go version devel +3922c006ad Fri Nov 22 15:34:14 2019 +0000 linux/amd64

Does this issue reproduce with the latest release?

Yes

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

go env Output

What did you do?

Suspect this falls under the banner of #35777

Unfortunately, per #35689 (comment), this is not reproducible.

Thanks. Folding into the super-bug. I'm not 100% positive about the go/build failure, but the vet failure is clearly the same corruption issue. (Closing since this one isn't reproducible.)
