Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target Milestone|--- |9.0 --- Comment #22 from Jonathan Wakely <redi at gcc dot gnu.org> --- It still needs to be fixed, and hoping for a libc fix isn't going to work because even if we get a solution in glibc it won't work for other C libraries. So we need to reimplement our std::call_once. I'll make sure we get this done for GCC 9.
