Error of double free or corruption

[kdeltak]

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?
