only a subset of C++14 (which msvc-14.0 supports) is required

do you have an idea why' compile test_coroutine.cpp : ...' works

but

run test_coroutine.cpp :
    [ requires cxx11_constexpr
               cxx11_decltype
               cxx11_deleted_functions
               cxx11_explicit_conversion_operators
               cxx11_hdr_tuple cxx11_lambdas
               cxx11_noexcept
               cxx11_nullptr
               cxx11_template_aliases
               cxx11_rvalue_references
               cxx11_variadic_macros
               cxx11_variadic_templates
               cxx14_initialized_lambda_captures ] ;

fails with:
