Anyone knows what this runtime error is about?

>      MFC71.dll!AfxTermExtensionModule(AFX_EXTENSION_MODULE & state={...}, int bAll=1)  Line 185 + 0x4      C++

void AFXAPI AfxTermExtensionModule(AFX_EXTENSION_MODULE& state, BOOL bAll)
      // make sure initialized
      if (!state.bInitialized)

      // search for CDynLinkLibrary matching state.hModule and delete it
      ASSERT(state.hModule != NULL);
      AFX_MODULE_STATE* pModuleState = AfxGetModuleState();
      for (CDynLinkLibrary* pDLL = pModuleState->m_libraryList; pDLL != NULL; )
            CDynLinkLibrary* pNextDLL = pDLL->m_pNextDLL;
            if (bAll || pDLL->m_hModule == state.hModule)
                  delete pDLL;    // will unwire itself     <------------------------------ Line 185
            pDLL = pNextDLL;

      // delete any local storage attached to this module
      AfxTermLocalData(state.hModule, TRUE);

      // remove any entries from the CWnd message map cache

Many thanks..
