octomap_mapping launch error

edit

I tried following command to use octomap server:

$ roslaunch octomap_server octomap_mapping.launch

then an error occurred.

My launch file is as follows:

<launch>
<node pkg="octomap_server" type="octomap_server_node" name="octomap_server" output="screen">
    <param name="resolution" value="0.1" />

    <!-- fixed map frame (set to 'map' if SLAM or localization running!) -->
    <param name="frame_id" type="string" value="/map" />

    <param name="base_frame_id" type="string" value="/footprint" />

    <!-- maximum range to integrate (speedup!) -->
    <param name="sensor_model/max_range" value="70.0" />

    <!-- data source to integrate (PointCloud2) -->
    <remap from="cloud_in" to="/velodyne_points_world" />
</node>
</launch>

The error message is as follows

process[octomap_server-1]: started with pid [9979]
octomap_server_node: malloc.c:2451: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.

What is the problem??
