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)
}
}https://drive.google.com/file/d/0B20Uwp8Hs1oCTzlVWFBmZ2lHS0k/view?usp=sharing
The program hangs (waited for several minutes, while file size is 502 bytes).
