Comment (by viboes):

 The problem is at least on the default constructor.

 I added the default initialization as zero, but this is not correct.

 Please, could you try the following

 {{{
 #if  defined   BOOST_NO_CXX11_DEFAULTED_FUNCTIONS
         BOOST_FORCEINLINE BOOST_CONSTEXPR
         duration() : rep_(duration_values<rep>::zero()) { }
 #else
         duration() BOOST_NOEXCEPT = default;
 #endif
 }}}


 You would surely need


 {{{
 #if  defined   BOOST_NO_CXX11_DEFAULTED_FUNCTIONS
         duration& operator=(const duration& rhs) // = default;
         {
             if (&rhs != this) rep_= rhs.rep_;
             return *this;
         }
 #else
         duration& operator=(const duration& rhs) = default;
 #endif
 }}}
