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.

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).

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,

These reports make us aware that we have found new issues with
newer tool chains on older LTS trees  / branches.

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.

Thanks for explaining the details here.
If I come across any fixed patch / commit id then I will share that information.
