[boost] bizarre test results: foreach, gcc-4_0-darwin

I need help understanding some of the recent regression results. At http://tinyurl.com/72q3k you can see the most recent Foreach test results. The first and the third columns both purport to be gcc-4_0-darwin, but the results are different! How can that be? Both tests were run today, and I haven't touched the code since yesterday. -- Eric Niebler Boost Consulting www.boost-consulting.com
