Make sure that you built dtl.lib and the example program using the
same microsoft runtime C library. For example

msvcprtd.lib

stands for the microsoft visual C++ runtime debug. Make sure the
example and lib project were built with the same compile flags for
the C++ runtime library they are using (e.g. Multi-threaded debug,
or whatever).
See previous posts in the forum on this. I really need to add this
to the FAQ.

------
The problem is that the linker tries to combine different,
incompatible versions of the Visual C++ runtime library into a single
binary. This happens when not all parts of your project and the
libraries you link against are generated with the same code
generation options in Visual C++.
