我目前正在Ubuntu Ubuntu 22.04.3上使用ROS 2 humble和一个rosbag pointcloud。然而，现在当我启动节点时，我得到了一个**[ros2run] Segmentation fault**。我只得到了错误，当我试图用PCL 1.12.1可视化点云时。如果我注解掉查看器，这个错误没有发生。2你知道什么可能导致这个问题，我如何修复它吗？

#include <rclcpp/rclcpp.hpp>
#include <sensor_msgs/msg/point_cloud2.hpp>
#include <pcl_conversions/pcl_conversions.h>
#include <pcl/point_cloud.h>
#include <pcl/visualization/cloud_viewer.h>

class SimplePointCloudSubscriber : public rclcpp::Node
{
public:
    SimplePointCloudSubscriber() : Node("simple_point_cloud_subscriber")
    {
        subscription_ = this->create_subscription<sensor_msgs::msg::PointCloud2>(
            "/velodyne_points", 10, 
            std::bind(&SimplePointCloudSubscriber::pointCloudCallback, this, std::placeholders::_1));
    }

private:
    void pointCloudCallback(const sensor_msgs::msg::PointCloud2::SharedPtr msg)
    {
        RCLCPP_INFO(this->get_logger(), "Received PointCloud2 message");
        pcl::PointCloud<pcl::PointXYZ>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZ>());
        pcl::fromROSMsg(*msg, *cloud);
        viewer_.showCloud(cloud);
    }

    rclcpp::Subscription<sensor_msgs::msg::PointCloud2>::SharedPtr subscription_;
    pcl::visualization::CloudViewer viewer_{"Simple Cloud Viewer"};
};

int main(int argc, char **argv)
{
    rclcpp::init(argc, argv);
    rclcpp::spin(std::make_shared<SimplePointCloudSubscriber>());
    rclcpp::shutdown();
    return 0;
}
