template <class T>
const T& get_constant_one_over_epsilon()
   static const bool is_init = false;
   static T result;
   if (is_init == false)
      typedef typename mpl::front<typename T::unsigned_types>::type ui_type;
      result = static_cast<ui_type>(1u);
      eval_divide(result, std::numeric_limits<number<T> >::epsilon().backend());

   constant_initializer<T, &get_constant_one_over_epsilon<T> >::do_nothing();

   return result;

is_init is never set to true.

Not sure what happened there, none of that initialization code was quite right. Should all be consistent and fixed now.
