Hello Nuno,
As far as I understood you correctly you are running your application in the debug (pressing f5 in VS) and release mode (outside the VS), if yes than please remember that Release Mode != Debug Mode, those two bytecodes are different. It might be the case that you have some optimization settings active in the release mode so I would suggest to get rid of any optimization coz it might be the cause why the program behaves differently.
I hope this will help
Good Luck

Hello Nuno,

I have encountered the same problem, when I was using ipopt as part of psopt.

I found that the problem is caused by the vs2008 "Optimization" settings of 2 projects when building the ipopt solution. If "Optimization" for the release version of the "CoinBlas" project and the "CoinMumpsF90" project is disabled when building the ipopt lib, the problem was solved!

I hope this may help you.

Regards, Ronald.

Subject: [Ipopt] Different result depending on running environment.


I'm trying to figure out why does my application behave differently depending whether it runs inside visual studio (debugging - F5) or outside visual studio (without debugging CTRL+F5).
When debugging, the program succeeds, and when not debugging it exceeds the maximum number of iterations.

Anyone has any idea?
(Note: these observations are independent of compiling with debug or release configuration)
