+与我们经常接触了题目不同，这是一个静态链接程序，运行时不需要加载 libc。not stripped 也为调试提供了便利。
+
+```
+$ ./readme_revenge

+Hi, aaaa. Bye.
+$ ./readme_revenge 
+%x.%d.%p
+Hi, %x.%d.%p. Bye.
+$ python -c 'print "A"*2000' | ./readme_revenge
+Segmentation fault (core dumped)
+```
+我们试着给它输入一些字符，结果被原样打印出来，而且看起来也不存在格式化字符串漏洞。但当我们输入大量字符时，触发了段错误，这倒是一个好消息。
