Dear All,

I wonder if anyone has ever meet this error when launching Hydrus simulation?

free(): double free detected in tcache 2

(I Googled, but could not find direct reason with ROS.)

System: Ubuntu 18.04 / ROS Melodic Build succeeded without errors. Tested branch: new master; 1.2.0 (both are same problem)

I attached the terminate output here.

Thanks in adavance!

Please use gdb to probe the error point: add launch-prefix="gdb -ex run --args" in https://github.com/JSKAerialRobot/aerial_robot/blob/master/robots/hydrus/launch/bringup.launch#L58
Try to clean your old workspace and rebuild

After using gdb and googled the output, I found the reason is because of gcc version. When I reset gcc version and rebuild, it goes well.

Thank you very much @tongtybj !
