Memory leaks detected by address sanitizer

[fmauch]

Describe the bug Running the tests using address sanitizer yields a couple of memory issues. I don't post the output as it is very long and can be easily reproduced using the steps below.

The following tests FAILED:
          1 - test_controller_manager (Failed)
          2 - test_controller_manager_with_namespace (Failed)
          3 - test_controller_manager_hardware_error_handling (Failed)
          4 - test_load_controller (Failed)
          5 - test_controllers_chaining_with_controller_manager (Failed)
          6 - test_controller_manager_srvs (Failed)
          7 - test_controller_manager_urdf_passing (Failed)
          8 - test_release_interfaces (Failed)
          9 - test_spawner_unspawner (Failed)
         10 - test_hardware_spawner (Timeout)
         11 - test_hardware_management_srvs (Failed)
         12 - test_ros2_control_node (Failed)

To Reproduce Steps to reproduce the behavior:

1. Build ros2_control with asan enabled (e.g. by --mixin asan-gcc)
2. Disable new-delete-type-mismatch checks: export ASAN_OPTIONS=new_delete_type_mismatch=0 (they are thrown from rclcpp and make using asan quite useless otherwise)
3. Run the tests using colcon test --executor sequential --packages-select controller_interface controller_manager hardware_interface hardware_interface_testing joint_limits transmission_interface
4. See error

Expected behavior No issues raised by ASAN :-)

Environment (please complete the following information):

• OS: Ubuntu 24.04
• Version Jazzy / 08f666cc

Additional context This may be potentially related to #1089

Hi! Is it possible for me to work on this too?

[christophfroehlich]

Sure. First try to reproduce the errors, then let's discuss possible fixes if it is not obvious what to do..
