Well, since you are using Windows, you'd better ask Microsoft, not us ;) See

What is the error code you are getting when you try to add 33554431 vertices 
with igraph_add_vertices? Also, note that the parameter to igraph_add_vertices 
is *not* the ID of the vertex to add but the *number* of vertices to add.
