Never mind the above; I was doing something dumb. One of the graphs I  
had created was empty, and so graph[0] was being called on an empty  
graph.

Still, I'm not sure why that would actually cause a segfault. In fact,  
it wasn't the call that was causing the segfault but rather the  
assignment:

graph[0];  // okay
void foo* = graph[0];  // bus error

Anyway, at least it's working now...
