marc at kdab dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |marc at kdab dot com --- Comment #9 from marc at kdab dot com --- 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?).
