I am not sure whether these are available from NPSOL, but it would be very helpful for diagnostics if the Lagrange multiplier, derivative of constraints, and the augmented (calculated) Hessian matrix could be given in the output slot of a fitted model. My impression is that standard errors are also missing currently when constraints are present.
