[Ipopt] Rép : Unpredictable results with mac OS X Lion vecLib

[Stefan Vigerske]

Hi,

Best would be if you could open an Ipopt ticket and attach it there.

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).
