Well, I did say it was a quick look.  It seems the other possibility
is that sqp can return 0 if the qp solver returns 0 at the last
iteration and the solution appears to satisfy the optimality
conditions.  A return value of 0 from the qp solver appears to mean
that the optimum has been found.

But if you think something else is happening, then maybe you should
trace the behavior of the function yourself.  It is just a script...
