6511,Division by scalar should use enable_if<>,Sean Reilly <campreilly@…>,Gunter,"file: vector_expression.hpp lines 1409 through 1417 
function: operator/( vector, scalar)

Should be using the enable_if<> macros just like the operator*() in lines 1397 through 1407 (just above it).  Doing so allows further overloading of operator/() for other types.  Suggested change is...

Before:
{{{
#!python
    // (v / t) [i] = v [i] / t
    template<class E1, class T2>
    BOOST_UBLAS_INLINE
    typename vector_binary_scalar2_traits<E1, const T2, scalar_divides<typename E1::value_type, T2> >::result_type
    operator / (const vector_expression<E1> &e1,
                const T2 &e2) {
        typedef typename vector_binary_scalar2_traits<E1, const T2, scalar_divides<typename E1::value_type, T2> >::expression_type expression_type;
        return expression_type (e1 (), e2);
    }
}}}

After:

{{{
#!python
    // (v / t) [i] = v [i] / t
    template<class E1, class T2>
    BOOST_UBLAS_INLINE
    typename enable_if< is_convertible<T2, typename E1::value_type >,

    >::type
    typename vector_binary_scalar2_traits<E1, const T2, scalar_divides<typename E1::value_type, T2> >::result_type
    operator / (const vector_expression<E1> &e1,
                const T2 &e2) {
        typedef typename vector_binary_scalar2_traits<E1, const T2, scalar_divides<typename E1::value_type, T2> >::expression_type expression_type;
        return expression_type (e1 (), e2);
    }
