[Ipopt] Continuing with the portfolio optimization problem

[Stefan Vigerske]

Hi,

ok, probably it is caught inside Ipopt already, I suspect line 581 of 
IpIpoptApplication.cpp.
However, with the default print_level it should have printed an message 
about what is wrong with the TNLP, because there is an
    exc.ReportException(*jnlst_, J_ERROR);
What is the output of Ipopt?
(Maybe you need to run from a command line to see it?)

Best,
Stefan
