You can't mix debug/release builds because they link to different 
runtime libs.

However, you can disable optimization in your release build. This gets 
you proper debugging in your code while everything else is fast (and not 
debuggable...)

I often do this on a file-to-file basis using #pragma optimize("", off) 
when I need debug a singular function in release. Doing it for the 
entire project is perhaps what you're looking for?
