Thank you very much for your prompt reply！

One thing I don't quite understand is that if we modify the test case as
suggested as the extra note, then the value of temp_v may vary at each
execution, then what is the occasion to use an atomic capture structure with 2
statements? Could you please give me an example of a practical usage of it?
