Error of double free or corruption

Open kdeltak opened this issue 4 years ago • 1 comments

Hello.

I am trying to use the laserscan_multi_merger to merge 2 laserscans. I run laserscan_multi_merger, but I have a trouble with double free or corruption. Do you have any tips for this error?

[Install ira_laser_tools] sudo apt-get installl ros-melodic-ira-laser-tools

no idea, but from your output data I see "devel_isolated"; is your ROS installed with apt-get or compiled from source? could you try to download to your src folder ira_laser_tools from here and un-install the apt version?
