when loading image, there is core dump when video reaches its end.

Hi

I run this script:

./darknet detector demo cfg/combine9k.data cfg/yolo9000.cfg ../yolo9000-weights/yolo9000.weights -prefix IL /data/videos/ILSVRC2015_train_00755001.mp4 -thresh 0.15

It is found that it will have core dump when video ends.

Any ideas?

Looks like it's a memory issue. Do you have enough RAM?
