            Bug ID: 35204
           Summary: std::chrono exception specification of explicitly
                    defaulted default constructor does not match the
                    calculated one
           Product: clang
           Version: 5.0
          Hardware: PC
                OS: Windows NT

Hello all,

it seems to be that the following code is accepted by MSVC while clang gives an
error on the same thing.

#include <atomic>
#include <chrono>

struct A {
   std::atomic<std::chrono::time_point<std::chrono::system_clock>> t{};
};



"clang-cl.exe" -fms-compatibility-version=19 -Werror -Weverything
-Wno-c++98-compat   /EHsc  t.cpp 


"cl.exe"  /EHsc  t.cpp

exception specification of explicitly defaulted default constructor does not
match the calculated one



In file included from t.cpp:1:
\Vs2015\VC\include\atomic(513,2):  error: exception specification of explicitly
