With attached t1.m code (and var1.txt.gz data):


load var1.txt
[p, obj_qp, INFO, lambda] = qp (x, B, c, F, g, [], [], d, C,
                                    Inf (size (d)), struct ("TolX", tol))


In 7.3:


octave:1> t1
p =

  -1.0443e-05
            0
   1.2300e-06

obj_qp = -2.8758e-10
INFO =

  scalar structure containing the fields:

    solveiter = 2
    info = 0

lambda =

         0
         0
         0
         0
   16.8016
         0


and in 8.2.1 (and 9.0.0)


octave:1> t1
p =

   2.8049
   2.3026
   0.1975

obj_qp = 2.8504e+11
INFO =

  scalar structure containing the fields:

    solveiter = 0
    info = 2

lambda = [](0x0)


this probably explain test failures in stk package (e.g. the one in windows
bundle).
