Hi Peter, Thanks for the bug report. I've checked in a fix for this to CVS. With the fix, your parents() function should look like this: std::pair parents(VertexID v, TaskGraph &tg) { InEdgeIterator e,e_end; tie(e,e_end) = in_edges(v,tg); ParentsIterator c(e, &tg),c_end(e_end, &tg); return make_pair(c,c_end); } I've also added documentation, the file libs/graph/doc/inv_adjacency_iterator.html, and fixed up adjacency_iterator.html a bit. Cheers, Jeremy On Mar 10, 2004, at 2:20 AM, Peter Aronsson wrote:

I'm sorry, but could I ask you to post a complete C++ program so that I can immediately reproduce the problem.

Thanks, Jeremy

Sure, Here is a shortened version that should produce the error on tg.cpp:62
