[ros-users] Convert sensor_msgs/Image to the opencv image

I'm trying to convert sensor_msgs/Image to the opencv image. The
sensor_msgs/Image is defined in the ros service as follows.
The problem has happened at the following code.
IplImage* left_image = bridge_.imgMsgToCv((const
sensor_msgs::ImageConstPtr&) srv.response.left_image, "passthrough");
Without the casting,(const sensor_msgs::ImageConstPtr&), there was an
compile error. With the casting, there is a runtime error, segmentation
fault. Is there anyone to know how to get the
sensor_msgs::ImageConstPtr& of the sensor_msgs/Image which is defined in
the ros service?
I confirmed that there are the proper value of each pixel in the
srv.response.left_image.data as well as srv.response.left_image.width
Thank you for any comments.
