bug in ellglobalred()

["Prof. J. E. Cremona" <John.Cremona@nottingham.ac.uk>]

The following is wrong:

         GP/PARI CALCULATOR Version 2.2.12 (development CHANGES-1.1375)
            i686 running linux (ix86/GMP-4.1.4 kernel) 32-bit version
     compiled: Nov  2 2005, gcc-3.4.3 20041212 (Red Hat 3.4.3-9.EL4)
               (readline v4.3 enabled, extended help available)


(16:29) gp > ellglobalred(ellinit( [0,0,0,-13980,313328]))
%1 = [42816, [1, 0, 0, 0], 24]

-- the conductor should be 128448, i.e. the exponent of 3 should be 2
and not 1.

A fix would bemuch appreciated -- someone must have an idea of which
recent changes might have caused this.

John
