I did an update today, and among the packages that were updated were: sys-devel/binutils to 2.15.92.0.2-r9 sys-apps/baselayout to 1.11.12 I am including baselayout because it is somewhat important, but I don't think the problem is there. I did a reboot and after the reboot: 1) X refused to startup, SIGSEGV upon initializing the GLX extension. Re-emerging did not help. I disabled GLX and it started. 2) mplayer segfaults on startup. I tried reemerging it, did not help. Everything was working smoothly till just that update ( and reboot ), so my guess is that the problem is in binutils. Reproducible: Always Steps to Reproduce: 1.emerge sys-devel/binutils-2.15.92.0.2-r9 2.Try to start X with GLX and get a SIGSEGV 3.Try to start mplayer and get a SIGSEGV Portage 2.0.51.22 (default-linux/x86/2005.0, gcc-3.4.3-20050110, glibc-2.3.5-r0, 2.6.11-gentoo-r8 i686) ================================================================= System uname: 2.6.11-gentoo-r8 i686 Intel(R) Pentium(R) 4 CPU 3.20GHz Gentoo Base System version 1.6.12 dev-lang/python: 2.3.5 sys-apps/sandbox: 1.2.8 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.5 sys-devel/binutils: 2.15.92.0.2-r9 sys-devel/libtool: 1.5.16 virtual/os-headers: 2.6.11 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-g0 -O2 -march=pentium4 -mtune=pentium4 -msse2 -pipe -fomit-frame-pointer -momit-leaf-frame-pointer -funit-at-a-time -ftracer -mfpmath=sse" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib/mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/texmf/web2c /etc/env.d" CXXFLAGS="-g0 -O2 -march=pentium4 -mtune=pentium4 -msse2 -pipe -fomit-frame-pointer -momit-leaf-frame-pointer -funit-at-a-time -ftracer -mfpmath=sse -fvisibility-inlines-hidden" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://gentoo.ITDNet.net/gentoo" LANG="en_US.utf8" LC_ALL="en_US.utf8" LDFLAGS="-Wl,-O1 -Wl,--sort-common -Wl,--strip-all" LINGUAS="en" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X aac acl acpi alsa apache2 avi bash-completion berkdb bitmap-fonts bonobo cdr crypt cups curl doc dvd dvdr eds emboss encode flac foomaticdb gd gdbm gif gnome gpm gstreamer gtk gtk2 guile hal howl imagemagick imlib ipv6 ithreads java jpeg junit kde kdeenablefinal ldap libg++ libwww mad mikmod mmap mmx motif mozilla mp3 mpeg mysql ncurses nls nptl nvidia ogg oggvorbis opengl pam pdflib perl pic plotutils png postgres pthreads python qt quicktime readline sdl session sharedmem slang spell sse sse2 ssl svga symlink tcltk tcpd tetex threads tiff truetype truetype-fonts type1-fonts unicode usb vorbis xml xml2 xv zlib linguas_en userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET
Update: 1) The problem did not go away after downgrading to -r8 2) The segfaults are not totally random. So far only X+GLX and mplayer show the problem.
I filed a separate bug on the mplayer part of the story, for the sake of debugging something concreate - http://bugs.gentoo.org/show_bug.cgi?id=92975
