<pre>Following is a reduction of an MSVC usage.
Following code compiles with GGC/MSVC, not with clang:
<a href="https://gcc.godbolt.org/z/ii2e2E">https://gcc.godbolt.org/z/ii2e2E</a>
t.cpp
=====
#include <any>
#include <type_traits>
struct V
{
V(std::any a) : a{a} {}
~V() = default;
V(const V &) = default;
std::any a;
};
static_assert(std::is_copy_constructible_v<V>);
run.sh
