[mesh_to_grid_map_node] died. mesh_to_grid

[aCodeDog]

When I launch quad_gazebo.launch file,it occurs： double free or corruption (out)

[ INFO] [1681922778.146408235]: Loading sim robot driver [INFO] [1681922778.183861, 0.000000]: Loading model XML from ros parameter robot_description_sdf [INFO] [1681922778.192351, 0.000000]: Waiting for service /gazebo/spawn_sdf_model [mesh_to_grid_map_node-3] process has died [pid 40533, exit code -6, cmd /home/wang/Quad-sdk/devel/lib/quad_utils/mesh_to_grid_map_node __name:=mesh_to_grid_map_node __log:=/home/wang/.ros/log/b4200fcc-ded1-11ed-b5fa-8d045a63f47b/mesh_to_grid_map_node-3.log]. log file: /home/wang/.ros/log/b4200fcc-ded1-11ed-b5fa-8d045a63f47b/mesh_to_grid_map_node-3*.log

And I found here in line 201: mesh_to_grid_map_converter.cpp has something wrong: pcl::PolygonMesh mesh_from_file; pcl::io::loadPolygonFilePLY(path_to_mesh_to_load, mesh_from_file);

But I don't know why this function causes this node died.

Sounds like something in your install didn't go quite right. That class prints the path to the world file it expects in the constructor (line 31) - can you verify that this path does actually point to a real .ply file? We may be missing an existence check which could cause an error like this.

@aCodeDog Any updates on this?

I have verified that this path does actually point to a real .ply file. I create a new cpp file to read it, and it works well. Maybe my Pcl lib has some problem. Finally, I re-install PCL, and everythins is ok.

May I ask which version of PCL you are using? I tried reinstalling PCL, but this issue still exists
