I was trying to use opencv_createsamples to create training samples for object detection. I used the following command:

/opt/ros/fuerte/bin/opencv_createsamples -vec lab_object.vec -img symbol.jpg -bg bg_lab.txt -num 300 -maxidev 30 -maxxangle 0.2616 -maxyangle 0.2616 -maxzangle 3.1417 -w 24 -h 24 -show

The execution stopped with the following console output:

Info file name: (NULL)
Img file name: symbol.jpg
Vec file name: lab_object.vec
BG  file name: bg_lab.txt
Num: 300
BG color: 0
BG threshold: 80
Invert: FALSE
Max intensity deviation: 30
Max x angle: 0.2616
Max y angle: 0.2616
Max z angle: 3.1417
Show samples: TRUE
Scale: 4
Width: 24
Height: 24
Create training samples from single image applying distortions...

The command worked two months ago. Can anyone tell me what does the error message (***** glibc detected *** /opt/ros/fuerte/bin/opencv_createsamples: free(): corrupted unsorted chunks**)signify? How can the error be removed (as the executable was formed while installing ROS)? I am using ROS- Fuerte on Ubuntu 12.04.
