<pre>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:
