I cut out most of the stuff not directly related to accessing the graph. It segfaults in the line marked by !!!, so it would seem that out_edges returns an invalid range (I did some debugging and the this line executes quite a few times before the iterator becomes invalid. I can't seem to force gdb to recognise nn1e as a symbol so I can't tell which edge/node is causing the problem. All this is ran after the graph is initialised (it's quite large, ab. 22k nodes and 900k edges).
You should include the definition of the graph's type. There are some subtle tradeoffs when selecting vecS vs. listS, etc.
Please disregard my previous message. Debugger sent me on a wild goose chase, the problem was in fact with property maps. Sorry about that. Regards, Greg
