Dynamically loading a DLL twice

I have in my Fortran code:

        dll_handle = LoadLibrary('Test123.dll'//char(0))

However this Fortran code may also be called from a C++ wrapper which may have already dynamically loaded this DLL.  From a quick test the Fortran call does not simply return the handle that the C++ wrapper got when it loaded it, but returns a different handle.  Has the DLL been loaded twice?  If so is this a problem?
