Comment:

 When you remove the vertex `v1`, the vertex descriptor `v2` is invalidated
 and thus no longer usable in operations such as `in_edges`.  See the
 **"Iterator and Descriptor !Stability/Invalidation"** section of
 http://www.boost.org/libs/graph/doc/adjacency_list.html for more
 information.  One fix is to set your vertex container to `listS` instead
 of `vecS`.
