[Coin-ipopt] ipopt 3.3.3 - segmentation fault

[Andreas Waechter]

Hi Adela,

In order to fix this, we would need more information in order to reproduce 
the prblem.

Please create a ticket at the Ipopt Trac pages (you will need to create an 
account for COIN if you don't have one yet and log in):

https://projects.coin-or.org/Ipopt

Please include all information necessary to reproduce what you see, such 
as Operating systems, compilers, and the exact sequence of commands that 
lead to this problem.  You can attach an AMPL model to the ticket (ideally 
a simple one) that ends up with the segmentation fault.

Thanks

Andreas
