libs/graph/example% ./components_on_edgelist.x

An undirected graph (edge list):

(0,1) (1,4) (4,0) (2,5)

Segmentation fault

------------END SNIP------------------

SO, what is the reason?

Thanks.

Arman.

Are there some work around ?

Actually I would like to construct disjoint sets based on vector<Edge>,
where Edge is pair<uint, uint>.

I fixed the various issues you are probably seeing with that example in the trunk just now; that version should work better. See if your code works with the new version.
