[Ipopt] Multiple TNLP Instances Segfault

[Stefan Vigerske]

Hi,

that sounds like a bug to me.
It would be good if you could open a ticket in the bugtracking system 
about this (login at https://projects.coin-or.org/Ipopt, then New 
Ticket), including some code snipets about what you tried. Best would be 
some code to reproduce the issue.

Stefan
