Erik Schnetter <schnetter at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |schnetter at gmail dot com --- Comment #7 from Erik Schnetter <schnetter at gmail dot com> --- I don't think that people didn't notice. I rather think that they gave up building the sanitizer. See also https://github.com/spack/spack/tree/develop/var/spack/repos/builtin/packages/gcc and https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/gcc/darwin/headers-10.13-fix.patch , which includes this fix automatically when GCC is built via Spack.
