处理点云程序段错误process has died [pid 31695, exit code -11, cmd /home

问题：

编写了一个处理点云的程序。编译全部通过，播放点云bag包后运行程序时报错：

[plane_fitter-1] process has died [pid 31695, exit code -11, cmd /home/lskk/ls_pc/devel/lib/plane_fitter/plane_fitter __name:=plane_fitter __log:=/home/lskk/.ros/log/5b94e870-573f-11ec-afbe-f02f74b2823c/plane_fitter-1.log].

 解决：

这种问题编写点云程序时经常遇到，今天记录一下。原因是程序中的点云序列号超出范围，可以理解为访问了无效内存，检查程序中访问点云序号的边界条件就可以解决，一般在循环/迭代语句中。
