valgrind: Mismatched free / delete and other leaks #1009
Description
Bug report
valgrind reports a mismatched delete in rcl_subscription_fini.part.0 (subscription.c:193) and a couple of "definitely lost" leaks. Not sure if this originates in rclcpp pr rclc. See full valgrind log below.
Required Info:
- Operating System: Ubuntu 22.04
- Installation type: binaries
- Version or commit hash: humble
- DDS implementation: (default)
- Client library (if applicable): rclcpp 16.0.1 / rcl 5.3.2
Steps to reproduce issue
Run the talker with valgrind:
valgrind --leak-check=full /opt/ros/humble/lib/demo_nodes_cpp/talker
Expected behavior
No issues reported
