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

go1.10.3 linux/amd64

Does this issue reproduce with the latest release?

Yes.

What did you do?

I tried to go build the following file:

package a

func f() (int, int, named int) {
	return 0, 0, 0
}

What did you expect to see?

Something like

./a.go:3:27: mixed named and unnamed return values

What did you see instead?

./a.go:3:27: duplicate argument int

The error message is correct. You're declaring three named integer return values, with the names int, int, and named respectively.
