[ros-users] [Discourse.ros.org] [Next Generation ROS] Ros2 LifecycleNode memory corruption issues

[Snowman]

We are experimenting with ROS2 and the LifecycleNode and started to observe crashes in our code. When we use regular nodes everything seems to be working fine. I tried to use valgrind to see what might be happening and indeed there are many warnings coming out from the tool (see some of the stuff below). 

I guess my question is - in what shape is the lifecycle package and are you guys aware of these problems? 

Thanks :)
