Solution about error "double free or corruption (out)" in Ubuntu 18.04 environment
Is your feature request related to a problem? Please describe. When running the repo codes in Ubuntu 18.04, it always reports "double free or corruption (out)" error. GDB finds out that the error is from "dataset.emplace_back(std::make_shared<VisualLiDARData>(data_path, bag_name));" in the codes, more specifically, from libiridescence.so.
Describe the solution you tried This bug is due to the "-march=native" flag in Iridescence compilation. What we should do is turn on the cmake option "BUILD_WITH_MARCH_NATIVE" in CMakelists.txt of Iridescence repo and re-make (install) it. Then the viewer of this calibration program can work!
Thanks for the detailed issue report. I guess you manually built and installed PCL (or some other libraries)? The error may stem from an inconsistent use of -march=naive option for dependency libraries. Mixing libraries built with/without -march=native causes segfaults. While "apt"-installed libraries are built without this flag, manual installation often enables it.
Yes I manually installed pcl 1.10 since the Ubuntu 18.04 built-in pcl library is 1.8. I think you are right that this error is caused due to the mismatching -march=native flags in different libraries.
Thanks for confirming. I think this information is useful for people in the community.
您的功能请求是否与问题有关？请描述。 在 Ubuntu 18.04 中运行 repo 代码时，它总是报告“double free or damage (out)”错误。GDB 发现错误来自代码中的“dataset.emplace_back(std::make_shared(data_path, bag_name));”，更具体地说，来自 libiridescence.so。
描述您尝试过的解决方案 此错误是由于 Iridescence 编译中的“-march=native”标志造成的。我们应该做的是在 Iridescence repo 的 CMakelists.txt 中打开 cmake 选项“BUILD_WITH_MARCH_NATIVE”并重新制作（安装）。然后此校准程序的查看器就可以工作了！
请问我已经在iridescence/CMakeLists中打开了option(BUILD_WITH_MARCH_NATIVE "Build with -march=native" ON)，并且重新编译安装了，运行时依然是"double free or corruption (out)已放弃 (核心已转储)",我的环境是18.04,下载源码编译的PCL 1.10，请问应该如何做呢？ 我的输入是：adc@adc:~/direct_visual_lidar_calibration$ rosrun direct_visual_lidar_calibration preprocess /home/adc/rosbag /home/adc/direct_visual_lidar_calibration/src/direct_visual_lidar_calibration/result -adv double free or corruption (out) 已放弃 (核心已转储）
我觉得你需要先用gdb确认一下报错是否来自libiridescent.so或者其他地方@XiaoHa0914 你好，我不确定我使用gdb是否正确，这是我的输入和输出：adc@adc:~$ ulimit -c 1000 adc@adc:~$ rosrun direct_visual_lidar_calibration preprocess /home/adc/rosbag/ /home/adc/direct_visual_lidar_calibration/src/direct_visual_lidar_calibration/result -adv double free or corruption (out) 已放弃 (核心已转储) adc@adc:~$ gdb direct_visual_lidar_calibration preprocess core Excess command line arguments ignored.
