compress/flate: hang (original) (raw)

The following program:

package main

import ( "bytes" "compress/flate" "encoding/hex" "io/ioutil" )

func main() { data, _ := hex.DecodeString("344c4a4e494d4b070000ff2e2eff2e2e2e2e2eff") _, err := ioutil.ReadAll(flate.NewReader(bytes.NewReader(data))) if _, ok := err.(flate.InternalError); ok { panic(err) } }

hangs at:
