Comment(by jewillco):

 The underlying C cos function has problems as well, even outside
 Boost.Interval.  This bug appears to be a manifestation of something like
 http://sourceware.org/bugzilla/show_bug.cgi?id=3976 (which also applies to
 many other functions).  According to that discussion, though, the standard
 library is not required to respect round-down or round-up for
 transcendental functions at all.
