[Ipopt] Hessian approximation makes Matlab to crash

[hongkai dai]

Hi All,

I installed IPOPT-3.9stable on my 64 bit Ubuntu machine, with Matlab 
R2010b. I tried the examples in MatlabInterface/examples directory. All 
examples can pass except examplehs51.m, which uses hessian-approximation 
to compute the Hessian matrix. This program makes Matlab crash. I 
revised other examples to use hessian-approximation, and they also 
crash. Is there anything special with the Hessian matrix computation? 
The linear solver I am using is MA27.

Best,
Hongkai
