10778,VC14 CTP4 Atomic don't compile with boost::chrono durations which are not TriviallyCopyable,mjklaim@…,viboes,"This complete example does not compile in VC14 CTP4:

{{{

#include <atomic>
#include <boost/chrono.hpp>

std::atomic<boost::chrono::milliseconds> ms; // error C2338: atomic<T> requires T to be trivially copyable.

}}}


Using the standard library instead works as expected:


{{{

#include <atomic>
#include <chrono>


std::atomic<std::chrono::milliseconds> ms; // no error

}}}


The compiler is correct that boost::chrono::duration is not trivially copyable (as described on cppreference.com at least)
but it seems (from looking at the code) that it's mostly concept check code used in 
constructors definitions that trigger the problem.",Bugs,closed,Boost 1.58.0,chrono,Boost 1.57.0,Problem,fixed,,raad@…
