segfault from PCL SHOTEstimationOMP

edit

I have a seg fault problem. I tried to run it with valgrind but I can't figure what caused the problem from the results. I also tried gdb but the results aren't much better. I don't see where the problem came from.

Some context for seg fault

global:

pcl::PointCloud<PointType>::Ptr modelPtr (new pcl::PointCloud<PointType> ());
pcl::PointCloud<PointType>::Ptr model_keypoints (new pcl::PointCloud<PointType> ());

in main:

  if (pcl::io::loadPCDFile (model_filename_, *modelPtr) < 0)
  {
    std::cout << "pcl::io::loadPCDFile error" << std::endl;
    return (-1);
  }

in callback function:

  pcl::NormalEstimationOMP<PointType, NormalType> norm_est;
  norm_est.setKSearch (10);
  norm_est.setInputCloud (modelPtr);
  norm_est.compute (*model_normals);

  pcl::copyPointCloud (*modelPtr, sampled_indices.points, *model_keypoints);

  pcl::SHOTEstimationOMP<PointType, NormalType, DescriptorType> descr_est;
  descr_est.setRadiusSearch (descr_rad_);
  descr_est.setInputCloud (model_keypoints); 
  descr_est.setInputNormals (model_normals); 
  descr_est.setSearchSurface (modelPtr);
  descr_est.compute (*model_descriptors); //segfault

Any ideas what could be the cause of this problem?

Edit: gdb backtrace results are here.

Edit2: I also get this warning from building this node

But line 15 is #include <pcl/visualization/pcl_visualizer.h> so it will be probably unrelated.
