否则，如果两个线程试图同时执行增加，操作的不幸交叉将导致计数器只被实现了一次，而不是被实现两次。
Otherwise, if two threads tried to execute the increment simultaneously, an unlucky interleaving of operations would result in the counter being incremented only once, instead of twice.

这对交叉编译尤其不利，因为您可能不能运行实际上是由交叉编译器创建的可执行程序。
This is especially pernicious for cross-compiling, since you probably can't run an executable actually created with the cross compiler.
