1.9.2, linux/amd64

package main

func main() {
	A := F{}
	C := F{}

type F struct{ b map[int]int }

func (f *F) Copy(f2 *F) { f.b = f2.b }

go vet warns: foo.go:6: possibly passing Go type with embedded pointer to C. Additionally, it prints the message twice.

Renaming C to B gets rid of the false positive.

Dup of #20655, and already fixed in 1.10.
