Comment(by guwi17):

 I tracked the source of the problem down to rounded_arith.hpp:93 where
 (-v) is computed although the type of v is and unsigned integer.

 Additionally I wonder why the constructor of interval<T> is
 template <T1, T2> interval(T1, T2) and not simply interval(T,T). The
 latter constructor would enforce the conversion to the correct type and
 prevent the shown bug.
