Reproducer:

package main

import "github.com/kortschak/utter"

func main() {
    r := make([]interface{}, 1)
    r[0] = r
    utter.Dump(r)
}

Also:

package main

import "github.com/kortschak/utter"

func main() {
    r := make(map[int]interface{}, 1)
    r[0] = r
    utter.Dump(r)
}

What about my favorite singularity? ;-)

package main

import "github.com/kortschak/utter"

type t []t

func main() {
    r := make(t, 1)
    r[0] = r
    utter.Dump(r)
}

That works now. map[int]t won't though.
