Hi Jeremy,
Ok, I know what caused this. There's a bug in that STL implementation... they have the wrong return type for std::set::find. I've changed it... though I don't have VC++ handy, so you'll have to tell me if it worked.
Tests running now... <rant> As an aside (and NOT for 1.31.0) it would be nice to hold the execution time down on some of the graph tests. Both bfs and dfs take a long time. For example, dfs takes around 45 seconds on my 3.0 Ghz machine. Multiply that by 7 compilers, and you get the idea. 45 seconds of time on a 3.0 Ghz box is an vast number of computations. Probably more test cycles than all the programmers in the world got in a day in 1965. We ought to be able to write 100% coverage test cases that none-the-less run quickly. </rant> OK, test finished, and it passes the three compilers in question. I'll rerun the full Boost tests, and post results shortly. Thanks, --Beman
