I've been porting working code from fuerte to groovy and ran into a strange crash in ros_pcl, since both are based on pcl1.6 it seems that this is may be a Groovy induced bug. The below code crashes with an "Illegal Instruction" when filter() is called on the VoxelFilter. Any ideas whats going wrong?

void pointCloudCallback (const sensor_msgs::PointCloud2Ptr& input) {
    std::cout << "Input cloud size " << input->data.size() << std::endl;
    if(input->data.size() <= 0){

    sensor_msgs::PointCloud2::Ptr cloud (new sensor_msgs::PointCloud2);
    sensor_msgs::PointCloud2 downSampledInput;

    //Downsample input point cloud
    pcl::VoxelGrid<sensor_msgs::PointCloud2> downsample;
    downsample.setLeafSize(0.20f, 0.20f, 0.20f);
    downsample.filter(downSampledInput);     //Illegal Instruction here

    //Transform into base_link
        pcl_ros::transformPointCloud(string("/base_link"), downSampledInput, *cloud, *_tfListener);
    catch(tf::TransformException ex){
        ROS_ERROR("TFException %s",ex.what());

Crash occurs even when pcl::VoxelGrid<pcl::PointXYZ> is used with converted point clouds. Call stack is the same

Do you have the most recent version of the pcl libs? There was an update 2 or 3 days ago which fixed an error causing "Illegal instruction" errors.

Which packages are you referring to? So since my initial post I've updated the machine from Ubuntu 12.04 to 12.10, purged all of ROS and did a reinstall using the Quantal packages. Then ran

sudo apt-get install ros-groovy-pcl*

Still getting illegal instruction crashes

Hey, sorry, I ignored that you are on groovy. The groovy packages were updated yesterday I think. So you should try to update again.

Hey, I ve got the same issue, but moving on.. My System: Ubuntu 12.04 LTS Intel® Core™2 Duo CPU E6550 @ 2.33GHz × 2 with 4GB RAM
