panic on recover (panic: reflect: call of reflect.Value.IsNil on struct Value)

[ldez]

The following program sample.go triggers a panic:

package main

import (
	"log"
)

func main() {
	defer func() {
		r := recover()
		if r != nil { // <- panic here
			log.Print(r)
		}
	}()

	panic("Ho Ho Ho!")
}

Expected result:

$ go run ./sample.go
2021/01/29 15:17:18 Ho Ho Ho!

Got:

$ yaegi ./sample.go
sample.go:10:6: panic
