I recently started using Qt and up until now everything's ran very smooth. When I choose to debug my application from within Qt Creator (in either release or debug configuration), it runs just fine without any exceptions. When I only run my debug build of the application, I get no exceptions as well. Then, for some odd reason when I choose to run my release build of the application I get exceptions within my code, but I'm not understanding why I would get the exceptions only without the debugger attached, and without any #ifdef directives. When I run it and manually attach the debugger I have the same issue, yet directly debugging from within Qt Creator works.

I'm debugging on Windows 7, and my .pro file is as follows:
