How does typelib marshalling handle arrays? It's marshalling IDispatch,
and this parameter is in IDispatch::GetIDsFromNames().

Well, the invocation returns DISP_E_UNKNOWNNAME, which is a valid return
value for the function, but as the call is successful when using native
ole dlls the most obvious possibility is that the names array is being
incorrectly marshalled (which would lead to no matches being found).
