Memory leake trigered by the realsense pipeline code c++

rs2::pipeline p;

rs2::config cfg;
cfg.enable_device_from_file("test.bag");

// Configure and start the pipeline
p.start(cfg);
int i = 0;
while (i++<5)
{
   std::cout<<"i: "<<i<<std::endl;
   // Block program until frames arrive
   rs2::frameset frames = p.wait_for_frames();
   if( !frames)
     continue;

   // Try to get a frame of a depth image
   rs2::depth_frame depth = frames.get_depth_frame();

   if (! depth)
          continue;

   // Get the depth frame's dimensions
   auto width = depth.get_width();
   auto height = depth.get_height();

   // Query the distance from the camera to the object in the center of the image
   float dist_to_center = depth.get_distance(width / 2, height / 2);

   // Print the distance
   std::cout << "The camera is facing an object " << dist_to_center << " meters away \r";
 }
 p.stop();



The above code snippet is showing some memory leakes when I run valgrind.
Is it the way the code is written or it's a known library issue. Any help will be appreiated.
thanks
