When I use the function projectorLaser(), the core dumped.

I wirte a laserscanSub callback function which is used to process the laser scan.But when I try to projectroLaser the sensor_msgs::LaserScan to sensor_msgs::PointCloud, I get the result: Segmentation fault(core dumped).The code is as below:

void Scanprocess::laserscanSubCallback(const sensor_msgs::LaserScanConstPtr &msg)
{
    if (msg == NULL)
    {
        ROS_INFO("msg is a nullptr.");
        return;
    }
    std::cout << msg << std::endl;
    projector_->projectLaser(*msg, cloud_in_scan_);
}

I find the reason is :aborting core dump writing, size exceeds current limit 1048576.The address of msg is bigger than the limit.Could someone give me some suggestions?

Start with Scanprocess::laserscanSubCallback and the projector_->projectLaser(*msg, cloud_in_scan_) call shown in the report. Reproduce the callback with the reported LaserScan input and inspect where the segmentation fault occurs; done means projecting the scan completes without a core dump and produces the expected PointCloud.
