--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- 6.2.1 stands for a 6 branch snapshot in between the 6.2 and 6.3 releases. Most of those snapshots of course don't have that fix, only those from the last day and half or so do. 6.3 is planned to be released in less than 2 weeks if all goes well.
