Hi Bill,

I assume you are talking about sqp. This function needs some love, as
it has several failures that have not been solved for a long time.
If you can make your problems specific, we (even better, you!) could
fill another bug report on the functions. They will be eventually
fixed, sqp is a really important part of nonlinear optimization.
