--- Comment #9 from Marc Poulhiès <dkm at gcc dot gnu.org> --- Yes, sorry I should have added that in my original message (I did mention the commit on IRC). This is the commit that introduces the hardcfr.c file that is miscompiled. The error may be latent and bisecting should probably run the above command with a copy of a preprocessed hardcfr.c ?
