These were mainly memory issues. Mr Hecht later found that it was due to some incompatibilities in the file : Ipopt-3.10.2/Ipopt/src/LinAlg/IpBlas.cpp. When used with mac OS X Lion's vecLib BLAS, some of the functions are passed values which lead to unpredictable results (as said in the following page : <a href="http://www.mathkeisan.com/usersguide/man/dcopy.html">http://www.mathkeisan.com/usersguide/man/dcopy.html</a>).</div><div>I don't know if someone already reported this, but having found nothing about that while doing a quick search, I thought it would be a good thing to do it. </div><div>Best regards.</div><div><br></div><div><br><div>
