You can work around this issue by changing the runtime library of your Debug application from /MDd (multi-threaded DLL debug) to /MD (regular, release version of the multi-threaded DLL runtime).

Your code will still be unoptimized and easier to debug than a normal release mode, but you will lose some debugging information (for example for crashes within the C runtime). You also lose some debugging features like the debug heap, but if you don't know what that is then it won't affect you.

To do this work around, just go to Properties>C/C++/Code Generation and change "Runtime Library" from /MDd to /MD.
