Several libraries are showing new test failures. Please check out the test results to see if your library has started to fail. If it is your problem, fix it or at least create a ticket for yourself:-)
If it is a Microsoft problem, consider submitting a bug report and posting a notice on the Boost list so that other developers are aware of the problem. Also post a link to the bug report on https://connect.microsoft.com
Looks like Variadic templates are still broken in VC++. Following code works on Сlang and GCC: template <typename... Ts, int... Is> std::string operator()(const std::tuple<Ts...>& tup, indices<Is...>) { std::ostringstream ost; ost << "( "; (void) (int []){0, (ost << printer()( std::get<Is>(tup) ), 0)... }; ost << ") "; return ost.str(); } But VC++ 14.0 gives a compilation error: ..\libs\variant\test\recursive_variant_test.cpp(88): error C2059: syntax error: '{' See https://github.com/boostorg/variant/blob/develop/test/recursive_variant_test... for a full test case. Another failure is in https://github.com/boostorg/variant/blob/develop/test/variant_reference_test... ..\libs\variant\test\variant_reference_test.cpp(88): error C2784: 'boost::add_reference<T>::type wknd_get(boost::variant<T,> &,int)' Unfortunately could not report those issues to https://connect.microsoft.com, web site does not respond.
At my request, Tom Kent has kindly added VC++ 14.0 (toolset msvc-14.0) to his develop branch tests.
Great thanks to both of you! -- Best regards, Antony Polukhin
