系统环境: CentOS 6.10 64bit

gdb调试时, 发现有如下错误提示信息:

(gdb) run
Starting program: /var/workspace/linux/high_perf/process/a.out

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7a8fd0c in vfprintf () from /lib64/libc.so.6
Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.212.el6.x86_64

解决方法:

1. 修改 /etc/yum.repos.d/CentOS-Debuginfo.repo 里面的 [base-debuginfo] 中的enable=1
2. yum install nss-softokn-debuginfo --nogpgcheck
3. debuginfo-install glibc-2.12-1.212.el6.x86_64
4. 如果3失败, 执行 第5步
5. yum install yum-utils
6. 执行第3步

再用之前的调试方法, gdb输出类似如下:

(gdb) run
Starting program: /var/workspace/linux/high_perf/process/a.out

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7a8fd0c in _IO_vfprintf_internal (s=<value optimized out>, format=<value optimized out>,
    ap=<value optimized out>) at vfprintf.c:1641
1641              process_string_arg (((struct printf_spec *) NULL));

可以发现已经没有开始的错误提示了.

注意

1. 第3步可能由于网络原因会很慢甚至失败, 不行就多试几次.
