[boost] Help needed with some Math lib failures

Folks, There are a few failures from Boost.Math (for example http://tinyurl.com/clvlq3) which I'm unable to reproduce locally - it seems only certain (possibly AMD x86-64 machines running Linux or *BSD) exhibit the problem. I can provide a test case to help with debugging what's going on, but I need to find someone who can reproduce the issue first. So... if you think you can help, then cd into libs/math/test and do a: bjam gcc test_hypergeometric_dist0 test_hypergeometric_dist1 test_hypergeometric_dist2 test_hypergeometric_dist3 test_hypergeometric_dist4 test_hypergeometric_dist5 and if one or more fail then let me know the failure message and I'll put together a test case. Many thanks in advance! John.
