free() invalid pointer at startup (workaround available)

[jveijck]

OS: Ubuntu 20.04 Running Groot after download from git (2022-07-29). After fixing build issues for non ROS2 system (ament fails and later the submodule BehaviorTreeV3 was not found correct). then I was enable to build Groot.

I starts and I can select "Editor | Monitor | Replay". If I select "editor", groot crashes with the message: "free() invalid pointer at startup". If a run it with "valgrind ./Groot" it starts up correctly(slow, but it starts). Valgrind reported several errrors:

When I use commit: b61e6feff117694788e59be48f39ec778e6e9c01 then I starts without any issues. The last commit imports a newer version of behavior trees. Most likely this is triggering the issue.
