I get good results with Version 2.1.4 on RedHat 7.3

                  GP/PARI CALCULATOR Version 2.1.4 (released)
                i686 running linux (ix86 kernel) 32-bit version
               (readline v4.2a enabled, extended help available)

   realprecision = 28 significant digits
   seriesprecision = 16 significant terms
   format = g0.28

parisize = 40000000, primelimit = 1000000

%1 = x + (y + 1)
