>Description:
gcj -C will generate dead bytecode from this source:

public class err8 {
  public static void main(String[] args) {
    do {
      break;
    } while (true) ;

  }
}

The generated code looks like this:

  0: goto 6
  3: goto 0
  6: return

This isn't very important, so I've marked it non-critical.
