Gulp indeed. Wrong AND corrupt (the last t_POL is an invalid object).

Fixed in svn: both stable and unstable/testing branches.

Thanks !

P.S: Btw, the preferred way to report bugs in PARI/GP is through our Bug
Tracking System, see http://pari.math.u-bordeaux.fr/Bugs/Reporting.html
This way everything is archived in a central place.

It's as simple as sending an email to submit@pari.math-u-bordeaux:

  Subject: Pari says 'Goodbye'


  Package: pari
  Version: 2.4.3
  Severity: wishlist

  When exiting, gp mutters a bland, contrived, and frankly quite unpersonal
  'Goodbye'. I suggest the more appropriate
  
      So long and Thanks for all the fish.

  Here is a transcript:

  
  Reading GPRC: /home/diligent/.gprc ...Done.

        GP/PARI CALCULATOR Version 2.4.3 (development svn-11392)
              i686 running linux (ix86 kernel) 32-bit version
               compiled: Dec  8 2008, gcc-4.2.3 (4.2.3-6mnb1)
  [...]
  (10:07) gp > quit
  Goodbye!

  I suggest that the output string, in src/gp/gp.c:gp_quit(), be corrected.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The first two lines ("Package": either pari, pari-stable or gp2c; and "Version")
are required.

The "Severity: wishlist" is optional. You get a regular bug report if you
omit it.
