Comment (by jewillco):

 On lines 121 and 124, you are using `*tv` even after that vertex might
 have been deleted (on 121, it is known to have been deleted).  Your
 comment about `*fv` being invalid after `*tv` has been removed is correct;
 in a graph with `vecS` vertex container, removing one vertex invalidates
 all other vertex descriptors.
