OculusRoomReallyTiny - cut down / simplified minimal sample

That looks like a problem with the CRT options used to compile the Oculus SDK libs and the sample. I believe both my sample and the Oculus libs are set to use the non-DLL versions of the CRT by default (/MT for Release or /MTd for Debug for the static Runtime Library rather than /MD or /MDd for the DLL version). I'm not sure why you're running into that error but that's where I'd look first. I'll try building on a fresh system with a clean install of the SDK when I get a chance and see if I can figure out the issue. Honestly I've found the whole setup with how you're supposed to build and link LibOVR.lib is kinda confusing, especially when trying to build my app with VS2015, so maybe I've screwed something up in the setting somewhere.
