Add in a clever programmer who decides to save some RAM (which makes sense in many cases, like if the shared item is a massive string of 50 MB) by not copying the data to a locally scoped variable, but keeps directly reading it, and you are going to see s

再加上一些聪明的程序员可能为了节省内存，不把数据拷贝到局部变量范围而是直接去读取，那么你就更会看到一些奇怪东西了。
