      It appears that if you link against mongoclient.dll in your project and then execute code that uses a static variable that's declared in the header but has storage reserved in the C++ driver, it may crash. The compiler seems to be allocating storage space for the static variable in the local application even though it should only be using the storage in the DLL.
