calling Symbols("") on new interpreter with stdlib.Symbols crashes with panic: reflect: call of MakeFunc with non-Func type

[rcoreilly]

The following program sample.go triggers an unexpected result

package main

import (
        "fmt"

        "github.com/traefik/yaegi/interp"
        "github.com/traefik/yaegi/stdlib"
)

func main() {
        i := interp.New(interp.Options{})
        i.Use(stdlib.Symbols) // commenting out this line prevents crash
        syms := i.Symbols("")
        fmt.Println(syms)
}

Expected result

$ go run ./sample.go

// lots of symbols here

Got

$ go run ./sample.go 
panic: reflect: call of MakeFunc with non-Func type
