<pre>MSVC compiles the following code, but Clang-CL rejects it:
class NonCopyable
{
public:
NonCopyable() {}
NonCopyable(const NonCopyable& other) = delete;
NonCopyable& operator=(const NonCopyable& other) = delete;
NonCopyable(const NonCopyable&& other) {}
NonCopyable& operator=(const NonCopyable&& other) {}
};
int main()
{
NonCopyable nc;
__noop(nc);
return 0;
}
....
C:\dev\src\playground\cpp\foo.cpp(17,9): error : call to deleted constructor of
'NonCopyable' [C:\dev\src\playground\cpp\build\cpptests.vcxproj]
__noop(nc);
^~
C:\dev\src\playground\cpp\foo.cpp(7,2): note: 'NonCopyable' has been
explicitly marked deleted here
