bug in qfminim() with pari 2.2.11 (current cvs) 

Hi,
gp > M=[4032, -378, 2268, 756, 3150, 756, 504; -378, 8736, 5796, 756, -378, 756, -966; 2268, 5796, 7560, 756, 2268, 756, 504; 756, 756, 756, 1512, 756, 756, 756; 3150, -378, 2268, 756, 4032, 756, 1386; 756, 756, 756, 756, 756, 1512, 756; 504, -966, 504, 756, 1386, 756, 1680] 

gp > qfminim(M,2*1512,0)
  *** qfminim: negative number of vectors in minim0.

and this is with


                     GP/PARI CALCULATOR Version 2.2.11 (development CHANGES-1.1316)
                      amd64 running linux (x86-64/GMP-4.1.3 kernel) 64-bit version
                                    compiled: Sep 11 2005, gcc-3.4.4
                            (readline v4.3 enabled, extended help available)


nb: works with 2.2.10 (alpha) and gives the answer: [42, 2940, [;]]

Cheers, Philippe.
