bug report


Hello.  I just (twice) got an error starting from a clean invocation of gp
2.0.17 (under Redhat Linux 6.1) after the following computations:

? ec=[0,0,0,-Mod(1,13),-Mod(3,13)]
%1 = [0, 0, 0, Mod(12, 13), Mod(10, 13)]
? c=ellinit(ec,1)
%2 = [0, 0, 0, Mod(12, 13), Mod(10, 13), 0, Mod(11, 13), Mod(1, 13), Mod(12, 13), Mod(9, 13), Mod(5, 13), Mod(11, 13), Mod(6, 13)]
? c.disc
%3 = Mod(11, 13)
? c.roots
  ***   segmentation fault: bug in GP (please report).

I'm just doing as requested: reporting the error.  Enjoy!
