Whatever, to me this very looks like a compiler bug.

So NACK to this one for now.

If this still happens on the latest tree (e.g. 6.4-rc) and with gcc 13, 
we might need to fix fortify or report to the gcc bugzilla [1] instead 
-- attach a preprocessed source there (the output of your make 
CROSSblabla=xyz drivers/net/wireless/ath/ath9k/main.i).
