Comment (by pbonami):

 Hi Jonathan,
 I have modified the status codes for continuous problems so that your
 problem should get the right status (unsolved).

 Let me know if you agree this is the correct status now (it is in trunk).

 Best,
 Pierre

 does this problem occur. Jonathan

 for the hessian approximation option of Ipopt (then Ipopt goes to
 iteration limit and status is not recognized). Is this correct? (i.e. when
 I disable the option everything seems fine to me).
