Answer 1

You are likely using different C runtimes in the libraries and your application. Check the project settings. Libcmt is the staticically linked multi-threaded run-time, while msvcrt is the dynamically linked version.

Check that the settings match in your project properties under

C/C++->Code Generation->Runtime Library
