--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- The question is also how much of explicit thread safety is needed when the init is now happening inside libstdc++ (thus from _init which should be already ensured to execute exactly once)? Is that (_init time) done for all targets/configurations btw?
