--- Comment #12 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Erich Löw from comment #10) > Envs: > > GCCVERSION=15.0.1 > CCFLAGS=-pipe -march=native -O2 -fPIC -fomit-frame-pointer > > $GCCVERSION is initialized as this: > export GCCVERSION=`gcc -dumpfullversion` Unset CFLAGS, CPPFLAGS, CCFLAGS and CXXFLAGS and try again. I suspect stage1 compiler is being miscompiled by the older compiler. And having C*FLAGS set is causing that. By default stage1 compiler is built without any options to avoid being miscompiled by the host compiler.
