This is true if you call add_vertex(g) on a subgraph to create a new vertex. If you however choose to add a already existing global vertex to the subgraph, this addition is not propagated to the parents of this subgraph. I assume this is a bug and fixed it. The patch is on github: https://github.com/j-4/graph/tree/fix-add_vertex-subgraph I also created a pull request! Thanks, Stefan PS: Attached is a unit test which fails due to this issue and runs through with the patched version!",Bugs,new,To Be Determined,graph,Boost Development Trunk,Problem,,subgraph,
