rPI camera + zBar = memory-leak

Seb26 (5)
Hi,

I'v trying to build a simple QR codes scanner using a Raspberry PI with camera and the zBar library.

That works but I have a memory-leak problem and I can't find it.

I'm using zbar-0.10 and raspicam-0.1.1

here is my source-code :

    // open camera 
    cout<<"Opening Camera..."<<endl;

   while(1)

      // capture a new frame
      Camera.grab();

      Image newCameraFrame(CAMERA_FRAME_WIDTH, CAMERA_FRAME_HEIGHT, "Y800", Camera.getImageBufferData(), Camera.getImageTypeSize(Camera.getFormat()) );
      
      int decodeResult = zBar_scanner.scan( newCameraFrame );
      if( decodeResult > 0 )
      {
         for( Image::SymbolIterator symbol = newCameraFrame.symbol_begin() ; symbol != newCameraFrame.symbol_end(); ++symbol )
         {  
            printf("QR = %s\n", symbol->get_data().c_str() );
         }            
      }
      else
      {
         printf("No data\n");
      }
   }
   
    return 0;
}


and here is my makefile :
1
2
 
all:
   g++ main.cpp -o Test_04 -Wall -I/usr/local/include -L/opt/vc/lib -lrt -lraspicam -lmmal -lmmal_core -lmmal_util -lzbar


when this program run, I can see (using top cmd on a remote shell) the RES value grow endless.

I feel that the problem is around the "Image newCameraFrame(...)" but cannot find how to solve that.

Thanks !

Seb

valgrind don't work fine on Raspberry PI ...
