SEGFAULT when adding a second Create3 Robot

[Gior26]

Describe the bug
Using the roni-kreinin/multi_robot fork from the pull request #207 the gazebo server encounters a SEGFAULT error whenever I try to add a second Create3 unit.

To Reproduce
Steps to reproduce the behavior:

1. ros2 launch irobot_create_ignition_bringup ignition.launch.py
2. ros2 launch irobot_create_ignition_bringup create3_spawn.launch.py namespace:=robot1
3. ros2 launch irobot_create_ignition_bringup create3_spawn.launch.py namespace:=robot2 x:=3.0
4. SEGFAULT on Gazebo server

Expected behavior
A second Create3 unit should spawn inside the simulation.

Additional context

• OS: Ubuntu 22.04.2
• Gazebo: Ignition Fortress
• ROS: Ros Humble

The first unit works correctly with the /robot1 namespace

@Gior26 You probably need to update your ign_ros2_control package. Version 0.4.4 fixes this issue.

Thanks, I've missed that dependency now everything works correctly.
I'm closing the issue.
