Ummm, interesting.

But is it solved?

Suppose developer a.n.other submits a patch that works with his/her GCC
version but doesn't with some other GCC version. I guess this will be
picked up in GIT build tests, but that only then tells everybody to
upgrade GCC or find a patch that fixes the issue (like you did, but I
couldn't find it).

Is there a document or something that stipulates what is the minimum
version[s] of GCC to build a particular version of the kernel? If not,
perhaps this is something that needs addressing.
