It works when I change the opt.
At least when opt=z, r.Read() called from io.ReadAtLeast() appears to fail.
// go
func ReadAtLeast(r Reader, buf []byte, min int) (n int, err error) {
if len(buf) < min {
return 0, ErrShortBuffer
}
for n < min && err == nil {
var nn int
nn, err = r.Read(buf[n:])
n += nn
}
if n >= min {
err = nil
} else if n > 0 && err == EOF {
err = ErrUnexpectedEOF
}
return
}
