Subject: [boost] [iterator][type_traits] A test is failing with gcc in c++03 mode

The zip_iterator_test_std_pair is failing with gcc in c++-03 mode. The
problem reduces viqa Boost type traits to the fact that in gcc c++03
mode the expression:
__is_abstract(std::pair<int&, std::string&>)
where __is_abstract is a compiler intrinsic, gives an error of:
error: forming reference to reference type
'std::__cxx11::basic_string<char>&'
pair(const _T1& __a, const _T2& __b)
^~~~
Is this a valid error according to the C++ 2003 standard ?
The test works in c++11 or c++14 mode.
