To my understanding, there is another way to acheive this :

If you select the Multi-threaded DLL (/MD) options, all allocations/deallocations, either from the main program or from the DLL are delegated to yet another DLL (MSVCR80.DLL) (which must then  be delivered with the program), and thus happen in a unique place.

Of course, the main program and all its DLL should be compile with the same option.
