技巧
当你用gdb来调试gdb的时候，通过设置命令提示符，可以帮助你区分这两个gdb：
$ gdb -q `which gdb`
Reading symbols from /home/xmj/install/binutils-gdb-git/bin/gdb...done.
(gdb) set prompt (main gdb)
(main gdb) r -q
Starting program: /home/xmj/install/binutils-gdb-git/bin/gdb -q
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
(gdb)
注意，这里set prompt (main gdb)结尾处是有一个空格的。
