--- Comment #10 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to marc from comment #9) > The patch does no longer apply to current gcc-9-branch, which, however, > still has the problem. The_Atomic stuff is easy to spot, though, and I can > confirm this fixes it for me, too (though I guess it's a hotfix, and nothing > mergeable, otherwise it would already be merged?). The usual process is to apply to trunk and then backport to any relevant active branches. I will get to it hopefully during this weekend (it will then appear in 9.2 when that's released but be available from 9 branch snapshots in the meantime).
