It doesn't matter, weakly and strongly connected components are equivalent in 
an undirected graph.

Well, first you destroy the vector, effectively giving its allocated memory 
area back to the operating system, then you try to access the vector that you 
have just destroyed. You should release the vector using igraph_vector_destroy 
only if you don't need it any more.
