Seems we have an issue with compiler setttings as this was now caught in stub3 build:

https://github.com/thesofproject/sof/actions/runs/13980547833/job/39144648495?pr=9913

 /home/runner/work/sof/sof/workspace/zephyr/kernel/thread.c:456:2: error: arithmetic on a pointer to void is a GNU extension [-Werror,-Wpointer-arith]
        LOG_DBG("stack %p for thread %p: obj_size=%zu buf_start=%p "

The error is coming from Zephyr code, so I think we can proceed with merging this and file a bug to follow-up (either SOF or Zephyr, depending on whether our compiler settings are too strict in SOF, or whether there's a problem in main of Zephyr).

One new compiler error from udpated Zephyr code. I think we can merge this if a follow-up ticket is filed.

@tmleman can you log/fix this on Zephyr side and link here. Alternatively we could cast or do the arithmetic outside the LOG() ?

@lgirdwood @kv2019i The issue has already been reported in Zephyr: zephyrproject-rtos/zephyr#87475
