Answer 1

The error can be caused by mixing together debug builds and release builds in same executable or dll.

1. in the vs configuration manager, are some of your projects in debug mode and some in release mode?
2. is one of your release projects has the preprocessor symbol DEBUG or _DEBUG defined?
3. is one of your debug projects has the preprocessor symbol NDEBUG defined?
