--- Comment #2 from albin <albin at yahoo dot com> ---
Simpler example:
#include <cassert>
template <typename T>
struct Foo
{
T val;
};
class Bar {
public:
constexpr Bar() = default;
constexpr Bar(Bar const& other) { other.val_ = 42; }
constexpr int val() const { return val_; }
private:
mutable int val_{};
};
int main()
{
constexpr Foo<Bar> x{};
Foo<Bar> y{x};
assert(x.val.val() == 42);
}
