It was fixed by this commit: https://github.com/zephyrproject-rtos/zephyr/pull/79597/commits/3bead0e2ceaff1db4307cba9575aa1ffa877e685.

I verified that I did not get the warning when using this revision of picolib in in SDK v.2.9.0.

/v2.9.0/modules/lib/picolibc$ git checkout d492d5fa7c96918e37653f303028346bb0dd51a2

If this is fixed in v3.0.0 then I think this won't be a problem for us. We're still early in the development so I would tend to follow the latest releases until we're further in the development.

Hi Martin,

Thanks for reporting this. I'm able to reproduce the warning if I use SDK v2.8.0 or v2.9.0, but not v2.7.0 or the v3.0.0-preview tag. I'm currently checking internally if this is a known issue. Will update this thread as soon as I know more.

Best regards,

Vidar
