image/jpeg: unreadByteStuffedByte call cannot be fulfilled

[dvyukov]

Run the following program on the following input:

package main

import (
    "bytes"
    "image/jpeg"
    "io/ioutil"
    "os"
)

func main() {
    data, _ := ioutil.ReadFile(os.Args[1])
    img, err := jpeg.Decode(bytes.NewReader(data))
    if err != nil {
        return
    }
    var w bytes.Buffer
    err = jpeg.Encode(&w, img, nil)
    if err != nil {
        panic(err)
    }
}

It crashes with:
