[Ipopt] Derivative checker seems to be incorrect (Ross Miller)

[Edson Cordeiro do Valle]

    Well
This may be a case where you have misplaced the nonzero position in the 
sparse Jacobian structure.
Can you remove all the other equations and use only the "suspect" 
equation and make an individual derivative check in this equation.
Until now, all the cases where the derivative checker reports an error 
it was my fault.
Unless a modification in the Ipopt code introduced some bug in the 
derivative checker, which, in my opinion is unlikely to happen.
Regards
