Sorry for the repeated mails I am sending you. The file size was to big and got rejected by the mailing list. This attachment should go through however.

I ran some tests and sometimes it works, but on strange occasions the program crashes with what looks like an index out of range message...I tracked down the crash to line 205 of isomorphism.hpp in the function bool match(edge_iter iter, int dfs_num_k). I have no idea if this is an actual bug (I doubt it though) or what I'm doing wrong.
