While building Linux stable rc 5.15 arm with gcc-13 failed due to following warnings / errors.
I appreciate you attempting to build older LTS trees with newer compilers, but note that usually, as you are finding out, this doesn't work.
These reports make us aware that we have found new issues with newer tool chains on older LTS trees / branches.
Right now I've finally gotten support for gcc-12 in all active stable kernel trees, gcc-13 takes more work as you are finding out so I'm only testing with newer trees (6.1 and newer).
We have seen great work (fixes) for gcc-12 when it got released. I think I / We should not expect this with gcc-13 since it takes more work.
As I understand, stable-rc 6.1 testing with gcc-13 would be ok. other than stable-rc 6.1 branches 5.x and 4.x should be built with gcc-12.
So when you run into issues like this, that obviously work in newer kernel releases, a report doesn't do much, BUT a git commit id of what the commit that needs to be backported IS appreciated.
Thanks for explaining the details here. If I come across any fixed patch / commit id then I will share that information.
thanks,
