--- Comment #51 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Rainer Orth from comment #10) > Interestingly, a i386-apple-darwin16 bootstrap *does* work fine. That's because the keymgr does work for m32 binaries. It's never kept track of images for x86_64 (from 10.6+, anyway) I'm not sure if / when last I ever tried a static linked libgcc on m64.
