Does it compile if you move makeVChappy() into graph.h and declare it inline? At least this would mean graph.h clients need not worry.

I'm rather unsure about what is causing this, but I get an internal compiler error in Visual C++ 7.1 when using BGL in some specific circumstances.
I have a graph defined in class Graph defined as such:
typedef property<edge_feedback_t, bool> EdgeFeedback; typedef property<edge_sourcejack_t, IAudioOutputJack*, EdgeFeedback> EdgeSourceJack; typedef property<edge_destinationjack_t, IAudioInputJack*, EdgeSourceJack> EdgeDestinationJack; typedef EdgeDestinationJack EdgeProperty; typedef boost::property<boost::vertex_index_t, int> VertexIndexProp; typedef property<vertex_name_t, nsCOMPtr<IAudioModule>, VertexIndexProp> VertexProperty; typedef adjacency_list<listS, listS, bidirectionalS, VertexProperty, EdgeProperty> graphdata; typedef graph_traits < graphdata >::vertex_descriptor vertdsc;
This definition works fine in the graph.cpp file that implements the class Graph.
However, when I use graph.h in another cpp file, I get bizarre compiler errors: c:\Boost\include\boost -1_31\boost\mpl\aux_\preprocessed\plain\apply.hpp(50) : fatal error C1001: INTERNAL COMPILER ERROR
After some trial and error, I narrowed the problem down to needing to have a != between two oedge_iterators _somewhere_ in the cpp file including graph.h. Simply putting the following function into my other files will cause them to compile just fine:
void makeVChappy() { typedef graph_traits< Graph::graphdata >::out_edge_iterator oedge_iterator; oedge_iterator oiter, oend; oiter != oend; }
I'm a a complete loss as to how this could be happening, but since I have a work-around for now, I'm not going to push the issue too much further at the moment --- I just thought I'd bring this to your attention, and see if anyone knows of a more elegant solution.
