What did you do?

Attempt to run the following program (github repository version):

main.go

package main

import (
	"fmt"

	"github.com/evanj/go121bug/pkg"
)

func main() {
	out := &pkg.Router{}
	fmt.Println(out.Route)
}

pkg/pkg.go

package pkg

import "fmt"

type Router struct{}

func callClosure(closure func()) {
	closure()
}

// Route is the obs_pipelines router
func (r *Router) Route() {
	callClosure(func() {
		fmt.Println("getConfigVersion:", r.getConfigVersion)
	})
}

func (r *Router) getConfigVersion() {}

What did you expect to see?

Some output:

$ go run .
0x10248fcb0

What did you see instead?

$ /Users/evan.jones/.gimme/versions/go1.21rc2.darwin.arm64/bin/go run .
# github.com/evanj/go121bug
./pkg/pkg.go:14:37: internal compiler error: missing wrapper for pkg.getConfigVersion

Please file a bug report including a short program that triggers the error.
