Use Pantheios framework from dll

Question

I am trying to use the pantheios framework from within a C ++ dll. I have successfully built the dll and it runs through my test application (C ++ MFC Application).

I used implicit binding with the following:

#include <pantheios/implicit_link/core.h>
#include <pantheios/implicit_link/fe.simple.h>
#include <pantheios/implicit_link/be.console.h>

My DllMain initializes pantheios with the following calls:

extern "C" const char PANTHEIOS_FE_PROCESS_IDENTITY[] = "FinishingLineController";

BOOL APIENTRY DllMain( HMODULE hModule,
                   DWORD  ul_reason_for_call,
                   LPVOID lpReserved)
    {
        switch (ul_reason_for_call)
        {
        case DLL_PROCESS_ATTACH:
            {
            int panres =  pantheios::pantheios_init(); 

            if(panres < 0)
            {
                fprintf(stderr, "Failed to initialise the Pantheios libraries: %s\n", 
                        pantheios::pantheios_getInitErrorString(panres));

                return FALSE;
            }
            }
            break;
        case DLL_THREAD_ATTACH:
            break;
        case DLL_THREAD_DETACH:
            break;
        case DLL_PROCESS_DETACH:
            pantheios::pantheios_uninit();
            break;
        }
        return TRUE;
    }

When I execute the following code, I get

Microsoft C++ exception: stlsoft::winstl_project::windows_exception at memory location 0x0013da84

pantheios::log_DEBUG("Test logging");

I tried using an explicit join instead of the result.
