 Hi,

 if I run Ipopt on a problem where all variables are fixed and the
 equations are infeasible within the bounds, then Ipopt runs into a seg.
 fault at !IpIpoptApplication.cpp:658, p2ip_data does not get initialized
 completely and then p2ip_cq->curr_f() tries to read the primal values of
 an !IteratesVector that has not become allocated.

 Would be nice if this could be fixed for trunk in a way similar to as it
 is working for stable already. There IpTNLPAdapter.cpp:586 does not throw
 LOCALLY_INFEASIBLE, but NO_FREE_VARIABLES_AND_INFEASIBLE.

 My workaround is [https://projects.coin-
 or.org/GAMSlinks/browser/trunk/ipopt.patch here], but it is not really
 nice.

 Best,
 Stefan
