[Ipopt] Unpredictable results with mac OS X Lion vecLib

[Ray Zimmerman]

I mentioned that Ipopt does not work with vecLib on Lion at https://projects.coin-or.org/Ipopt/wiki/Ipopt_on_Mac_OS_X. My solution was to use Goto BLAS, which performed almost as well in my tests on Snow Leopard.

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 :  http://www.mathkeisan.com/usersguide/man/dcopy.html).
