original codes:
----------------------------
Lib3dsCameraNode* 
lib3ds_node_new_camera(Lib3dsCamera *camera) {
    Lib3dsNode *node = lib3ds_node_new(LIB3DS_NODE_CAMERA);    Lib3dsCameraNode *n;
    
    assert(camera);
    node = lib3ds_node_new(LIB3DS_NODE_CAMERA);
    strcpy(node->name, camera->name);    n = (Lib3dsCameraNode*)node;
    lib3ds_track_resize(&n->pos_track, 1);
    lib3ds_vector_copy(n->pos_track.keys[0].value, camera->position);    lib3ds_track_resize(&n->fov_track, 1);
    n->fov_track.keys[0].value[0] = camera->fov;    lib3ds_track_resize(&n->roll_track, 1);
    n->roll_track.keys[0].value[0] = camera->roll;    return n;
}-----------------------------
 
 
my fixed code:
 
 
Lib3dsCameraNode* 
lib3ds_node_new_camera(Lib3dsCamera *camera) {
    Lib3dsNode *node;    Lib3dsCameraNode *n;
    
    assert(camera);
    node = lib3ds_node_new(LIB3DS_NODE_CAMERA);
    strcpy(node->name, camera->name);    n = (Lib3dsCameraNode*)node;
    lib3ds_track_resize(&n->pos_track, 1);
    lib3ds_vector_copy(n->pos_track.keys[0].value, camera->position);    lib3ds_track_resize(&n->fov_track, 1);
    n->fov_track.keys[0].value[0] = camera->fov;    lib3ds_track_resize(&n->roll_track, 1);
    n->roll_track.keys[0].value[0] = camera->roll;    return n;
}
