I've just moved over a Visual Studio (C++) solution over to another computer, setup all the directories and settings as far as I can see, and did a clean/rebuild on the solution. I get the error above on a bunch of .obj's on compile, not sure what to do about it.
It seems that you are mixing object files built with different settings. Try to do a full clean rebuild and check all project file settings to make sure that the _ITERATOR_DEBUG_LEVEL macro is the same (e.g., you are not mixing debug and release built objects).
