Equality Constraints not working with dense qp

[dlcfort]

The optimization that I set up does not work when I set the number of general inequality constraints "ng" to zero. However when I set "ng" to a value of 1 it works fine. Is there something wrong with my formulation or is there a bug in the code? You can see from the printed vector (Av) at the end that it does not match up with the vector (b)
