--- Comment #2 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Iain Sandoe from comment #1) > please can you do "grep CFI" gccc/auto-host.h and put the output here? also what version of Xcode you're using and/or what version of GCC you are using to bootstrap. I built and installed all languages for the 9.1rc2 version - so unless there was a patch after than but before the release, this is a surprising fail..
