Teng Qingshan moved a box. Call location. Move the box down. However, this box is built on the ground. Said Teng Qingshan. "Bro. I have taken it all down. Time-consuming. So many tea bricks. I'm afraid it's going to fall ." Teng Qingshan looks cautiously. Slowly shake the box. Pour out all the tea bricks.
"Success !" Put the empty box on one side.
The soldiers immediately watched the empty box and tea bricks. At the same time, he said, "the other one is also qui

Look at the wiki today and see a mention of what's going to fall into race condition ABA problem. Ah, I have not heard of Aba Ah, then I went to search for a bit, as follows:Http://www.bubuko.com/infodetail-317006.html"SpinLock spin Lock, CAS operation (Compare Set) ABA problem"The ABA is explained as follows:The so-called ABA (see Wikipedia's ABA Entry), the problem is basically like this:

P1 was preempted, process P2 executed.

may cause some potential problems.The ABA problem is most likely to occur in the lock free algorithm. CAS bears the brunt of this problem because CAS judges the pointer address. If this address is reused, the problem will be very high.(Address reuse often occurs. After a memory is allocated, it is released and distributed. It is likely that the original address is still used)
