Describe the bug

Adding CONFIG_LOG_MODE_IMMEDIATE=y to prj.conf seems to crash the z_pub.c example

  1. Use Zenoh pico z_pub.c example
  2. Add CONFIG_LOG_MODE_IMMEDIATE=y to prj.conf
  3. Flash on STM32 F767
  4. Reset PCB, and picocom -b 115200 /dev/ttyUSB0
  5. Observe crash

I can't seem to reproduce on my end, could you also share your entire Zephyr config file?
