[igraph] problem of igraph_degree_sequence_game() ?

[fa]

Dear All:

When I build a degree sequence of (4,4,3,2,2,2,1) graph.
It will show crash,when I run it.

                         Thanks

----------------------------------------------------------------------------------
my code:


#include <igraph\igraph.h>
main()
{
igraph_vector_t degree_vector;
igraph_t network;
igraph_vector_init(&degree_vector,8);

igraph_vector_set(&degree_vector,0,4);
igraph_vector_set(&degree_vector,1,4);
igraph_vector_set(&degree_vector,2,3);
igraph_vector_set(&degree_vector,3,2);
igraph_vector_set(&degree_vector,4,2);
igraph_vector_set(&degree_vector,5,2);
igraph_vector_set(&degree_vector,6,1);
igraph_vector_set(&degree_vector,7,1);

igraph_degree_sequence_game(&network,&degree_vector,0,IGRAPH_DEGSEQ_VL);

igraph_vector_destroy(&degree_vector);
igraph_destroy(&network);
