malloc(): memory corruption on CvImage::toImageMsg

[Pyrojambo]

I've encountered an error when using the following line of code, which runs in a loop to publish at 20Hz:
sensor_msgs::ImagePtr img_ptr = cv_bridge::CvImage(std_msgs::Header(), "bgr8", img).toImageMsg();

I've used GDB to try to get more information on it and got the following:
