<pre>The following snippet fails to compile, with all 4 static assertions firing:
#include <type_traits>
struct foo { volatile int i; };
int main() {
static_assert(!std::is_trivially_copy_constructible<foo>::value,
"is_trivially_copy_constructible");
static_assert(!std::is_trivially_move_constructible<foo>::value,
"is_trivially_move_constructible");
static_assert(!std::is_trivially_copy_assignable<foo>::value,
"is_trivially_copy_assignable");
static_assert(!std::is_trivially_move_assignable<foo>::value,
"is_trivially_move_assignable");
}
I think it should compile fine, at least according to my reading of 12.8/12:
<span class="quote">> A copy/move constructor for class X is trivial if (...)
> - class X has no non-static data members of volatile-qualified type</span >
and 12.8/25:
<span class="quote">> A copy/move assignment operator for class X is trivial if (...)
> - class X has no non-static data members of volatile-qualified type</span >
These bullets were introduced by the resolution of CWG496.</pre>
