在 ARM 处理器上运行 pcl::MovingLeastSquares 代码时出现双重释放或损坏运行时错误

Question

我在运行 Ubuntu 13.04 的 ARM 处理器上运行移动最小二乘代码时遇到运行时问题， 从github手动编译最新的pcl 1.7.2。

在第 266 行崩溃了一个双重释放错误 surface/include/pcl/surface/impl/mls.hpp

其他相关包：

• LibBoost 版本 1.49.0.1

• FLANN 版本 1.7.1-4

• 特征 3.1.2-1

相同的代码在普通 PC（64 位 Ubuntu 12.04）上正常运行。

我从以下位置抓取并修改了代码： http://pointclouds.org/documentation/tutorials/resampling.php

这是我最终运行的基本代码：

#include <pcl/point_types.h> 
#include <pcl/point_cloud.h>
#include <pcl/io/pcd_io.h>

#include <pcl/kdtree/kdtree_flann.h>
#include <pcl/surface/mls.h>

using namespace pcl;
using namespace pcl::io;

// ######################################################################
int main(int argc, char **argv)
{
  // Load input file into a PointCloud<T> with an appropriate type
  PointCloud<PointXYZ>::Ptr cloud (new PointCloud<PointXYZ> ());
  pcl::io::loadPCDFile (argv[1], *cloud);

  // Create a KD-Tree
  pcl::search::KdTree<PointXYZ>::Ptr 
    tree (new pcl::search::KdTree<PointXYZ>);

  // Output has the PointNormal type 
  // in order to store the normals calculated by MLS
  PointCloud<PointNormal> mls_points;

  // Init object (second point type is for the normals, even if unused)
  pcl::MovingLeastSquares<pcl::PointXYZ, pcl::PointNormal> mls;

  mls.setComputeNormals (true);

  // Set parameters
  mls.setInputCloud (cloud);
  mls.setPolynomialFit (true);
  mls.setSearchMethod (tree);
  mls.setSearchRadius (0.03);

  // Reconstruct CRASH IN LINE BELOW
  mls.process (mls_points);

  return EXIT_SUCCESS;
}

下面是 gdb 跟踪。代码在 mls.process 行中崩溃：

提前谢谢你。

Answer 1

根据 Nizar Sallem 的建议，我禁用了矢量化 （在 pcl_config.h 中将其设置为 0，因为它几乎包含在每个位置）在调试模式下。 ==> http://www.pcl-users.org/double-free-or-corruption-error-in-pcl-MovingLeastSquares-on-ARM-processor-td4033241.html#a4033425

这就是我所做的：

我添加到 pcl-master1.7.2/CMakeList.txt

add_definitions(-DEIGEN_DISABLE_UNALIGNED_ARRAY_ASSERT 
                      -DEIGEN_DONT_VECTORIZE) 
add_definitions(-DEIGEN_DONT_ALIGN) 

在本征定义之后：

# Eigen (required) 
find_package(Eigen REQUIRED) 
include_directories(SYSTEM ${EIGEN_INCLUDE_DIRS}) 
add_definitions(-DEIGEN_USE_NEW_STDVECTOR 
                -DEIGEN_YES_I_KNOW_SPARSE_MODULE_IS_NOT_STABLE_YET) 

我也添加到了 pcl_config.h.in

#define EIGEN_DONT_VECTORIZE 1 
#define EIGEN_DONT_ALIGN 1 

在第 15 行之后：

#define PCL_VERSION_COMPARE(OP,MAJ,MIN,PATCH) \
      (PCL_VERSION OP PCL_VERSION_CALC(MAJ,MIN,PATCH)) 

这两个添加中的一个或两个都可以解决问题。
