The tools from the transcode package (except transcode itself) can not be executed if compiled with the gcc-4.1.1 using -O2 -fweb, but produce SEGV errors. As a workaround, I would recommend stripping -fweb (and -funroll-loops, which according to the gcc docs activates it) from the CFLAGS in the ebuild. I can't tell if it is a gcc bug or lies in the transcode sources itself. It seems that the code which triggers the SEGV is the cpuid-availability-detection code in the function "static int mm_support(void)" in aclib/cputest.c, which looks correct to me. As all x86_64 CPUs support cpuid anyway, one could alternatively use an #ifdef ARCH_X86 to check only on x86 CPUs, which works as well. gcc 4.1.1 on x86 compiles transcode with the -fweb without problems. emerge --info: Portage 2.1.1_rc1-r2 (default-linux/amd64/2006.1, gcc-4.1.1, glibc-2.4-r3, 2.6.18-rc5 x86_64) ================================================================= System uname: 2.6.18-rc5 x86_64 AMD Athlon(tm) 64 Processor 3500+ Gentoo Base System version 1.12.4 Last Sync: Fri, 01 Sep 2006 03:20:01 +0000 app-admin/eselect-compiler: [Not Present] dev-lang/python: 2.4.3-r3 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: [Not Present] dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.18.1 sys-devel/autoconf: 2.13, 2.60 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.17 sys-devel/gcc-config: 1.3.13-r3 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r3 ACCEPT_KEYWORDS="amd64 ~amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -march=athlon64 -fweb -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /lib/modules /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/gconf /etc/java-config/vms/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c" CXXFLAGS="-O2 -march=athlon64 -fweb -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig buildpkg distlocks metadata-transfer parallel-fetch sandbox sfperms strict" GENTOO_MIRRORS="ftp://ftp.easynet.nl/mirror/gentoo/ www.ibiblio.org/gentoo/" LINGUAS="de en en_GB en_US" PKGDIR="/usr/portage/packages/foxtrot" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude='/distfiles' --exclude='/local' --exclude='/packages'" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage /usr/local/overlays/layman/portage-xgl /usr/local/overlays/layman/break-my-gentoo-main" SYNC="rsync://echo.digadd.de/gentoo-portage" USE="amd64 3dnowex 7zip X a52 aac alsa amr apache2 avi bitmap-fonts bluetooth bzip2 cdda cddb cdio cdparanoia crypt cups dga dri dts dvd dvdr dvdread elibc_glibc emacs encode escreen ffmpeg firefox flac font-server foomaticdb freetype gd gif glitz gpm gtk gtk2 gtkhtml innodb input_devices_evdev input_devices_keyboard input_devices_mouse ipv6 jpeg kernel_linux libsamplerate linguas_de linguas_en linguas_en_GB linguas_en_US lm_sensors lzo mad matroska memlimit mikmod moznocompose moznoirc mp3 mp4 mpeg multislot mythtv ncurses nls no-seamonkey no_wxgtk1 nptl nptlonly nvidia ogg oggvorbis opengl pam parse-clocks pdf pic png pthreads readline sdk sdl sensord shaper snmp ssl symlink tetex theora threads tiff truetype truetype-fonts type1-fonts usb userland_GNU userlocales v4l v4l2 vcd video_cards_nv video_cards_nvidia vorbis wxwindows x264 xanim xine xinerama xml2 xmms xorg xosd xprint xv xvid xvmc zlib zvbi" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, MAKEOPTS, PORTAGE_RSYNC_EXTRA_OPTS

Same behaviour on my system. (~amd64 with gcc 4.1.1 and -fweb in my CFLAGS) The workaround (disabling cpuid) works fine.
AMD64, feel free to add the filter-flag if you think so.
it's getting filtered now
