drawTracks.C error in iclose

[Optimus1072]

Hi, I am trying to visualise the output by running drawtrac.c but I am getting " Error in `./drawTracks': double free or corruption (!prev): 0x0000000000dd5700". Can you help me out in figuring this out. will it be possible for you to share the output video so the visualisation part can be moved to newer libraries. I'll be interested in doing so. Further, from where to get image.g and libimage.so?.
