Can someone look at a testing regression in your graphviz test?
I've been trying to do some fixing up of the boost graph implementation since it has been needing some attention. Last night and this morning there were a number of regressions which I have not seen before. Could I get someone's feedback on what might be going on? These are only occurring on Mac -- Linux and Windows are all green.
