Somewhere in your code you must try to allocate memory for g_SettingsVersion. Check there to see if it worked (check for NULL return). Somewhere else you must try to acquire or allocate a handle for hTable (probably a resource). Check for NULL there, too.
If you don't know if the pointer or handle will be NULL when you try to free or lock, then check them before you use them.
