场景说明：RedHat6.4
在gdb调试boost库的时候，出现如下的错误：
Program received signal SIGSEGV,Segmentation fault.
0x0011c613 in boost::thread::start_thread()()
from /usr/local/lib/libboost_thread.so.1.49.0
Missing separate debuginfos, use:debuginfo-install glibc-2.12-1.80.el6.i686 libgcc-4.4.6-4.el6.i686 libstdc++-4.4.6-4.el6.i686
原因：
一言以蔽之，该指令和yum一样安装一些库文件，但是安装的库文件是携带gdb的调试。如下是debuginfo提供的源，如果debuginfo-install下载缓慢，可以直接使用迅雷下载：
http://debuginfo.centos.org/6/i386/
解决方案：
1）配置debuginfo的yum源，CentOS可能自带：
# CentOS-Debug.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# All debug packages from all the various CentOS-5 releases
# are merged into a single repo, split by BaseArch
#
# Note: packages in the debuginfo repo are currently not signed
#
[debug]
name=CentOS-6 - Debuginfo
baseurl=http://debuginfo.centos.org/6/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6
enabled=1
保存文件到/etc/yum.repos.d/目录下，名字：CentOS-Debug.repo
2)测试是否已经安装了debuginfo-install
debuginfo-install glibc
如果出现下面的问题,表明没有安装：
-bash: debuginfo-install: command not found
3）安装yum-utils，使用命令：
yum install yum-utils
可能安装的软件包比较多，可以单独安装：
# yum install nss-softokn-debuginfo --nogpgcheck
--nogpgcheck参数选项：忽略签名的检查
4）使用debuginfo-install指令，下载上面缺乏的调试库
