efaq: Reporting bugs

 
 2.5 Where should I report bugs and other problems with Emacs?
 =============================================================
 
 The correct way to report Emacs bugs is to use the command ‘M-x
 report-emacs-bug’.  It sets up a mail buffer with the essential
 information and the correct e-mail address, <bug-gnu-emacs@gnu.org>.
 Anything sent there also appears in the newsgroup <news:gnu.emacs.bug>,
 but please use e-mail instead of news to submit the bug report.  This
 ensures a reliable return address so you can be contacted for further
 details.
 
    Be sure to read the “Bugs” section of the Emacs manual before
 reporting a bug!  The manual describes in detail how to submit a useful
 bug report (SeeReporting Bugs (emacs)Bugs.).  (SeeEmacs manual,
 if you don’t know how to read the manual.)
 
    RMS says:
 
      Sending bug reports to the help-gnu-emacs mailing list
      (http://lists.gnu.org/mailman/listinfo/help-gnu-emacs) (which has
      the effect of posting on <news:gnu.emacs.help>) is undesirable
      because it takes the time of an unnecessarily large group of
      people, most of whom are just users and have no idea how to fix
      these problem.  The bug-gnu-emacs list
      (http://lists.gnu.org/mailman/listinfo/bug-gnu-emacs) reaches a
      much smaller group of people who are more likely to know what to do
      and have expressed a wish to receive more messages about Emacs than
      the others.
 
    RMS says it is sometimes fine to post to <news:gnu.emacs.help>:
 
      If you have reported a bug and you don’t hear about a possible fix,
      then after a suitable delay (such as a week) it is okay to post on
      ‘gnu.emacs.help’ asking if anyone can help you.
 
    If you are unsure whether you have found a bug, consider the
 following non-exhaustive list, courtesy of RMS:
 
      If Emacs crashes, that is a bug.  If Emacs gets compilation errors
      while building, that is a bug.  If Emacs crashes while building,
      that is a bug.  If Lisp code does not do what the documentation
      says it does, that is a bug.
