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.
