The debugging thread received SIGABRT when print a boost::shared_ptr variable.

[brillywu]

Here is the source code:

typedef ::sensor_msgs::PointCloud2_<std::allocator<void> > PointCloud2;
  typedef boost::shared_ptr< ::sensor_msgs::PointCloud2_<ContainerAllocator> > Ptr;
  typedef boost::shared_ptr< ::sensor_msgs::PointCloud2_<ContainerAllocator> const> ConstPtr;


void RayGroundFilter::CloudCallback(const sensor_msgs::PointCloud2ConstPtr& in_sensor_cloud)
{
  health_checker_ptr_->NODE_ACTIVATE();
  health_checker_ptr_->CHECK_RATE("topic_rate_points_raw_slow", 8, 5, 1, "topic points_raw subscribe rate slow.");

  sensor_msgs::PointCloud2::Ptr trans_sensor_cloud(new sensor_msgs::PointCloud2);
  const bool succeeded = TransformPointCloud(base_frame_, in_sensor_cloud, trans_sensor_cloud);
  if (!succeeded)
  {
    ROS_ERROR_STREAM_THROTTLE(10, "Failed transform from " << base_frame_ << " to "
                                                           << in_sensor_cloud->header.frame_id);
    return;
  }
.....
}

when break points hit, I move mouse to "trans_sensor_cloud", sometimes, it works well, sometimes it lets thread abort
