最近使用CodeLite（我使用的TDM-GCC 5.1.0版本编译器）写了个简单的C++程序，调试的时候发现，程序不进断点运行完就退出了，可编译器和调试器的设置都是对的啊。更诡异的是在命令行使用CodeLite调用的GDB程序直接调试程序却能正确的捕捉到断点。于是上网搜索，在StackOverflow上得到了一个回答，是这样说的：

尝试打开Settings -> Debugger Settings -> GNU gdb debugger -> Misc -> Enable debugger full logging选项来获取更详细的CodeLite与GDB之间的交互信息，这样就可以知道GDB停止运行的原因。输出的日志会打印在"Debugger"面板的"Output"标签页。

于是去勾选上调试器设置的“Enable debugger full logging”选项

F5调试源程序，在output标签中获得下面的日志输出

注意到错误信息 internal-error: cp_search_static_and_baseclasses: Assertion `name[prefix_len + 1] == ':'' failed.\n，根据这条错误信息我们查到了下面的相关的地址

通过这两个网页得到的信息，我们知道了是TDM-GCC 5.1.0带着的7.9.1版本的GDB的BUG，切换到以前的版本的GDB就行了。而且经试验当前最新的7.12版本也没有这个问题。至此，问题解决。
