[Coin-ipopt] Segmentation Fault (Quasi Newton option)

[Sonia Singhal]

Hi,

I am working with the 3.1.0 version of IPOpt and am using the Quasi
Newton option to approximate the Hessian.
After several (100) iterations IPOpt gives a segmentation fault. The
call stack is -

=======================================================
Program received signal SIGSEGV, Segmentation fault.

Someone else faced the same problem about a month back. Was wondering
if someone knows the reason or has a solution for this problem.

Thanks,
