Exporting map

[space03]

Hi.

I want to export the final map to pcd files.
From issues, i found the following comment.
#3 (comment)

1st Terminal: roslaunch loam_velodyne loam_velodyne.launch
2nd Terminal: rosbag play ~/Downloads/MY_BAG_FILE_NAME.bag
3rd Terminal: rosrun pcl_ros pointcloud_to_pcd input:=/velodyne_cloud_registered

but I'm in trouble. In 3rd terminal, exporting pcd file command is not working.

rosrun pcl_ros pointcloud_to_pcd input:=/velodyne_cloud_registered
[ INFO] [1553843254.665227026]: Publishing data on topic /cloud_pcd with frame_id /base_link.
Segmentation fault (core dumped)

Please help me. Thank you.

It is solved by rebooting the computer.

But i have other problems. I want to save the whole(full size) map.
But " rosrun pcl_ros pointcloud_to_pcd input:=/velodyne_cloud_registered" is saved only current window point cloud information.
Maybe it is similar problem with #41 (comment).

I dont have any idea of how to change original code of loam, laserMapping.cpp(~/catkin_ws/src/loam_velodyne/src/lib).
And is it correct that exporting map to pcd command is " rosrun pcl_ros pointcloud_to_pcd input:=/velodyne_cloud_registered"?
please help me.
