terminate called after throwing an instance of 'std::length_error'; what(): cannot create std::vector larger than max_size()

[Johannes-42]

Describe the bug I used microROS on my older Laptop, there it worked fine but now i switched to my newer PC and the microROS Agent crashes.

To Reproduce I run it with Zephyr and freeRTOS. I used the Tutorials from the official microROS webpage. https://micro.ros.org/docs/tutorials/core/first_application_rtos/zephyr/ (and equivalent freeRTOS tutorial) This means i used the ping_pong example.

When running the command: ros2 run micro_ros_agent micro_ros_agent serial --dev /dev/serial/by-id/usb-ZEPHYR_Zephyr_micro-ROS_203030335841500F-if00

i get the following output: [1707298293.366673] info | TermiosAgentLinux.cpp | init | running... | fd: 3 [1707298293.366786] info | Root.cpp | set_verbose_level | logger setup | verbose_level: 4 [1707298294.446095] info | Root.cpp | create_client | create | client_key: 0x1D96764C, session_id: 0x81 [1707298294.446130] info | SessionManager.hpp | establish_session | session established | client_key: 0x1D96764C, address: 0 terminate called after throwing an instance of 'std::length_error' what(): cannot create std::vector larger than max_size()

Expected behaviour Not crashing

System information (please complete the following information):

• OS: Ubuntu 22.04.3 LTS
• ROS 2 humble

• Olimex STM32 Boars like in the Tutorial

  Additional context It is the same for freeRTOS and Zephyr so it could be something with newer hardware. I also tried it with other examples but it will also crash.

Are you mixing humble and iron distros?

[Johannes-42]

I used ROS1 Noetic before on Ubuntu 20.04. Then i deleted that and upgraded to Ubunutu 22.04 and installed ROS2 humble.

Could you check that you micro-ROS agent is in humble also?

[Johannes-42]

I do not know how to do that. But i just removed ROS2 and my microROS folder and reinstalled ROS2. Now it is working. I probably set it (ROS2) up wrong somewhere.

Thanks for the help!
