 Hi,

 I observed that the values in g which are given to the call of
 TNLP::finalize_solution seem to be incorrect for equality constraints,
 i.e., for a constraint of the form c<=g(x)<=c. I can correct them by
 adding the constant c to the corresponding entry in g.
 From a look at TNLPAdapter::Eval_c, i see that c_rhs_[i] is substracted
 from some values, maybe it need to be added again in TNLPAdapter::ResortG.

 I'm using IPOPT release 3.2.3.

 All best,
 Stefan
