这几天做汇编实验，总是跳出这个warning，就想着找时间解决掉它。今天就来看看这个问题到底怎么解决。

同时运行结束还有这样应该报错

Missing separate debuginfos, use: debuginfo-install glibc-2.17-307.el7.1.x86_64

先百度一波 CRC mismatch

半小时过去，无果。

算了还是先看后面一句 Missing separate debuginfos

按照他的说法执行 sudo debuginfo-install glibc-2.17-307.el7.1.x86_64

漫长的等待…

大概二十几分钟过去了，安装结束，再次运行gdb发现前面的warning也没有了！

原因是什么呢？

有时间再更吧，先抓紧时间做实验了~
