[Ipopt] IPOPT issue solving consecutive problems (segmentation fault)

[Andreas Waechter]

Hi Dragos,

I could run your code through a memory checker, such as "valgrind" on 
Linux.  If it turns out that the segfault is indeed caused by Ipopt 
code, please submit a ticket with a bugfix or a simple program to 
reproduce the problem.

Thanks,

Andreas
