HPOFF stands for Hessian Pattern Offset

it is used to merge the sparsity pattern of the target funtion
with the sparsity pattern of the constraints.

Then you have probably really large problems ;-)

So it has been a while since I programmed it. Therefore, if I remeber it
right, the following should be true:

One could use in the allocation

instead of




this should provide enough space but might be
