Created attachment 335458 [details] build.log.xz This is from a clean stage3. The default stage3 has C[,XX]FLAGS="-O2 -pipe -mcpu=ev4". With -mcpu="ev67" it builds. gcc-4.7.2 builds fine though. The relevant part of the build.log is: make[2]: Entering directory `/var/tmp/portage/sys-devel/gcc-4.6.3/work/build' make[3]: Entering directory `/var/tmp/portage/sys-devel/gcc-4.6.3/work/build' rm -f stage_current make[3]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.6.3/work/build' Comparing stages 2 and 3 warning: gcc/cc1plus-checksum.o differs warning: gcc/cc1-checksum.o differs Bootstrap comparison failure! gcc/opts.o differs make[2]: *** [compare] Error 1 make[2]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.6.3/work/build' make[1]: *** [stage3-bubble] Error 2 make[1]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.6.3/work/build' make: *** [bootstrap-lean] Error 2 emake failed * ERROR: sys-devel/gcc-4.6.3 failed (compile phase): * emake failed with bootstrap-lean Portage 2.1.11.31 (default/linux/alpha/10.0, gcc-4.5.4, glibc-2.15-r3, 3.4.0-gentoo alpha) ================================================================= System uname: Linux-3.4.0-gentoo-alpha-EV68AL-with-gentoo-2.1 Timestamp of tree: Sun, 13 Jan 2013 01:45:01 +0000 ld GNU ld (GNU Binutils) 2.22 app-shells/bash: 4.2_p37 dev-lang/python: 3.2.3-r1 dev-util/pkgconfig: 0.27.1 sys-apps/baselayout: 2.1-r1 sys-apps/openrc: 0.11.8 sys-apps/sandbox: 2.5 sys-devel/autoconf: 2.68 sys-devel/automake: 1.11.6 sys-devel/binutils: 2.22-r1 sys-devel/gcc: 4.5.4 sys-devel/gcc-config: 1.7.3 sys-devel/libtool: 2.4-r1 sys-devel/make: 3.82-r4 sys-kernel/linux-headers: 3.6 (virtual/os-headers) sys-libs/glibc: 2.15-r3 Repositories: gentoo ACCEPT_KEYWORDS="alpha" ACCEPT_LICENSE="* -@EULA" CBUILD="alpha-unknown-linux-gnu" CFLAGS="-mieee -pipe -O2 -mcpu=ev4" CHOST="alpha-unknown-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/gconf /etc/gentoo-release /etc/sandbox.d /etc/terminfo" CXXFLAGS="-mieee -pipe -O2 -mcpu=ev4" DISTDIR="/usr/portage/distfiles" FCFLAGS="-O2 -pipe" FEATURES="assume-digests binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync news parallel-fetch protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" FFLAGS="-O2 -pipe" GENTOO_MIRRORS="http://distfiles.gentoo.org" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="acl alpha berkdb bzip2 cli cracklib crypt cups cxx dri fortran gdbm gpm iconv ipv6 modules mudflap ncurses nls nptl openmp pam pcre pppd readline session ssl tcpd unicode zlib" ALSA_CARDS="ali5451 als4000 bt87x ca0106 cmipci emu10k1 ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 maestro3 trident usb-audio via82xx ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="authn_core authz_core socache_shmcb unixd actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="kexi words flow plan sheets stage tables krita karbon braindump" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" PHP_TARGETS="php5-3" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python2_7 python3_2" RUBY_TARGETS="ruby18 ruby19" USERLAND="GNU" VIDEO_CARDS="fbdev glint mach64 mga nv r128 radeon savage tdfx dummy v4l" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, USE_PYTHON
I can also confirm that 4.6.3 fails to build on alpha with "emake failed with bootstrap-lean" CFLAGS="-mieee -pipe -O2 -mcpu=ev4"
It's PR56023 upstream
Fixed in 4.6.3 p1.11, queued for 4.7.2.
Fixed in 4.7.2 p1.4.
