shared_ptr will not (and cannot) autoconvert from a pointer. Explicitly
creating a shared_ptr naively from image in this case will cause shared_ptr
to try and delete that pointer, which will crash since that pointer is not
valid for deletion.

I believe you can do something like the following (untested):

sensor_msgs::ImageConstPtr image_ptr(disparity_msg, &disparity_msgs->image);

This will share the reference count with disparity_msg, but act like a
pointer to an Image.
