Yeah, that was one of the first things I tried:

for (Function::iterator i = function.begin(), e = function.end(); i !=  
e; ++i) {
	BasicBlock *basicBlockPtr = &(*i);
	add_vertex(basicBlockPtr, timingGraph);
}

The "&(*i)" sure seems weird, but I don't know how else to grab a  
pointer to the BasicBlock from within the iterator.

Also, if I then try to extract a vertex from the graph:

BasicBlock *basicBlockPtr = timingGraph[0];
			
...the whole thing segfaults. So I'm basically stuck.
