LoadLibrary succeeds on a computer that is running Windows 98, Windows NT, or Windows 2000 in this situation. However, the behavior of calling functions in the DLL that reference static TLS variables is undefined. On Microsoft Windows 95, LoadLibrary fails and the GetLastError function returns 1114 - ERROR_DLL_INIT_FAILED (A dynamic link library initialization routine failed). On Windows 2000, the LoadLibrary function succeeds. However, any attempt to access the TLS data causes an access violation (AV).
The DLL code should be modified to use such TLS functions as TlsAlloc, and to allocate TLS if the DLL might be loaded with LoadLibrary. Or, the DLL that is using __declspec(thread) should only be implicitly loaded into the application.
