Hi Edward,

Hmm, I can take a look later today. Which version of gcc is this with?

I am using mingw-64/gcc-6.2 on Windows. I will try it on Linux soon. If I use -std=gnu++03 instead of -std=c++03, it works without errors.

Thanks

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)

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.
