PointCloudCommon::update get segmentation fault in custom plugin

[QYChan]

Enviorment: ROS2 Humble/ Ubuntu 20.04
I am trying to develop my custom pointcloud visualization plugin with the PointCloudCommon class. The CustomPlugin::update() is as follow:

void CustomPlugin::update(float wall_dt, float ros_dt) {

    point_cloud_common_->update(wall_dt, ros_dt);
}

When calling the PointCloudCommon::update，the program segmentation fault occurs.
