binutils: Bug Criteria

 
 18.1 Have You Found a Bug?
 ==========================
 
 If you are not sure whether you have found a bug, here are some
 guidelines:
 
    * If a binary utility gets a fatal signal, for any input whatever,
      that is a bug.  Reliable utilities never crash.
 
    * If a binary utility produces an error message for valid input, that
      is a bug.
 
    * If you are an experienced user of binary utilities, your
      suggestions for improvement are welcome in any case.
