<pre>When testing clang-cl 6.0.0-RC2, I got some compilation errors on code which
compiled with 5.0.0 and MSVC2015
========= t.cpp ===========
#include <exception>
namespace
{
struct A : public std::exception
{
};
}
int main()
{
std::make_exception_ptr(A{});
return 0;
}
======== run.bat ==========
cl.exe /EHsc t.cpp /std:c++14
llvm_5_0_0\bin\clang-cl.exe -fms-compatibility-version=19 /EHsc t.cpp
/std:c++14
llvm_6_0_0-RC2\bin\clang-cl.exe -fms-compatibility-version=19 /EHsc t.cpp
/std:c++latest
======== result ===========
Vs2015\VC\INCLUDE\exception(369,27): error: function
'std::__GetExceptionInfo<(anonymous namespace)::A>' is used but not
defined in this translation unit, and cannot be defined in any other
translation unit because its type does not have linkage
template<class _Ex> void *__GetExceptionInfo(_Ex);
^
Vs2015\VC\INCLUDE\exception(373,65): note: used here
return exception_ptr::_Copy_exception(_STD addressof(_Except),
__GetExceptionInfo(_Except));
