I got the recent revision 61803.
The compilation is ok but the code is crashing on the line:
72   incremental_components(g, ds);
------------- SNIP --------------------
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.
