[Ipopt] Matlab crashes when running examplehs051.m

[hongkai dai]

Dear,

I have installed ipopt-3.9stable version on my 64bit Ubuntu machine, 
with Matlab2010b. I tried all the examples in the 
MatlabInterface/examples directory. All examples can produce an optimal 
result except examplehs051.m. Matlab will crash immediately as I run 
this file. Is there any reason for this? The only difference I can find 
between this example and others is that it uses a quasi-newton method to 
compute the Hessian matrix. Can this be the reason? Anyone has similar 
experience?

Best,
Hongkai
