--- Comment #12 from Jonathan Wakely <redi at gcc dot gnu.org> --- 13.1 has already been released, it can't be changed now. As comment 10 says, the fix is only on trunk so far and has not been backported to the gcc-13 branch. It will be in the next 13.x release after it's backported to that branch.
