Long ago, something changed in Boost.Random and several Accumulator tests started failing. It's not actually a bug (I don't think), just a bad assumption in the test about tolerances and pseudo-random distribution. I've never had time to fix it. I should probably just comment this test out or mark it as a known failure. </p> </description> <category>Ticket</category> </item> </channel> </rss>
