(**: 
   1. Is it necessary to tag [248] here
   For compatibility reasons: tag [248] will make 
   `Printexc.to_string` happy see #1501
   2. Is it okay to remove the negative value
   For marshalling? 
   3. Global exception is encoded the same as user defined exception 
   (for nullary and non-nullary), except
   - time stamp
   - its name is not qualified
