Unkown error to hector_costmap.cpp

[suho0515]

Hello sir, I'm trying to create hector_costmap. I made 2D Occupancy grid map and 2.5D Elevation Map but Cost map. but there is error like this

[hector_costmap-1] process has died [pid 40480, exit code -11, cmd /home/suho/catkin_ws/devel/lib/hector_costmap/hector_costmap __name:=hector_costmap __log:=/home/suho/.ros/log/56bc3842-4663-11ea-b940-40a3cce998a5/hector_costmap-1.log]. log file: /home/suho/.ros/log/56bc3842-4663-11ea-b940-40a3cce998a5/hector_costmap-1*.log

        // check if neighbouring cells are known
        if(elevation_map_.at<int16_t>(v+1,u) == (-elevation_zero_level) ||

                elevation_map_.at<int16_t>(v,u+1) == (-elevation_zero_level) ||
                elevation_map_.at<int16_t>(v,u-1) == (-elevation_zero_level))
    {
        printf("continue\n");
                continue;
    }`

I did review the code of hector_costmap.cpp and there is unknown error in some specific point. and i did print it out to see what's going on.

and i could get the result like this.

elevation_map_.at<int16_t>(1088,1122):0 elevation_map_.at<int16_t>(1086,1122):0 elevation_map_.at<int16_t>(1087,1123):0 elevation_map_.at<int16_t>(1087,1121):0 not continue min_index(1):925 max_index(1):1123 min_index(0):925 max_index(0):1123 v:1088 u:925 [hector_costmap-1] process has died [pid 40480, exit code -11, cmd /home/suho/catkin_ws/devel/lib/hector_costmap/hector_costmap __name:=hector_costmap __log:=/home/suho/.ros/log/56bc3842-4663-11ea-b940-40a3cce998a5/hector_costmap-1.log]. log file: /home/suho/.ros/log/56bc3842-4663-11ea-b940-40a3cce998a5/hector_costmap-1*.log

I could detect that, the node(hector_costmap) is terminated when the variable 'v' goes to 1088 or 1087. is there any memory issue, or should i configure something?

regards.

it caused by wrong setting, i'd close this issue.
