CentOS 6.4下使用Eclipse Juno CDT(4.2.2)的項目在編譯點調試後會彈出如下錯誤：
其中Details內容為：
Error in final launch sequence
Failed to execute MI command:
maintenance set python print-stack off
Error message from debugger back end:
Undefined maintenance set python command: "print-stack off". Try "help maintenance set python".
Undefined maintenance set python command: "print-stack off". Try "help maintenance set python".
後來經過google，大致是因為CentOS 6.4的gdb有升級，新版的gdb內刪掉了一下命令，而Eclipse Juno CDT又剛好使用了這些命令。

解決辦法：
降級gdb，降為CentOS 6.3使用的版本
# yum downgrade http://mirrors.163.com/centos/6.3/os/x86_64/Packages/gdb-7.2-56.el6.x86_64.rpm
