    {
        // Note: do_end() is now called from span::~span() before impl_ destruction
        // to ensure owner->impl_ is still valid when export_span is called.
        // This is necessary because libc++'s unique_ptr sets its internal pointer
        // to null before calling the deleter, which would cause owner->impl_ to
        // be null when export_span tries to access span data.
    }
