Hi Edward, Hmm, I can take a look later today. Which version of gcc is this with? Thanks On Dec 16, 2016 10:03 PM, "Edward Diener" <eldiener@tropicsoft.com> wrote:
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<ch ar>&' 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.
