Bad Input Bug. Fixed by checking the dimension first:

(17:52) gp >  qflll(matrix(2,3,x,y,x+y));
  ***   dependant vectors in lllfp.

I don't see a way to get a nicer error message for the related BIB:

(17:55) gp > qflll(matrix(3,3,x,y,x+y))
  ***   exponent overflow
[ dependant columns again, but no easy way to detect this... ]
