urlgrabber-3.9.1-r1 is working properly but urlgrabber-3.9.1-r2, migrated to using distutils-r1, and now results in a cp segmentation fault during the installphase if selinux is enabled. It installs properly if it is disabled at boot time. The culprit is the following command: "cp -a --reflink=auto /var/tmp/portage/dev-python/urlgrabber-3.0.1-r2/image//_python2.7/. /var/tmp/portage/dev-python/urlgrabber-3.0.1-r2/image//", called by multibuild_merge_root the last file cp is handling before segfaulting seems to be usr/bin/urlgrabber, at this point in the strace: lstat("/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image//_python2.7/./usr/bin/urlgrabber", {st_mode=S_IFLNK|0777, st_size=39, ...}) = 0 lstat("/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image/./usr/bin/urlgrabber", {st_mode=S_IFLNK|0777, st_size=39, ...}) = 0 stat("/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image//_python2.7/./usr/bin", {st_mode=S_IFDIR|0755, st_size=20, ...}) = 0 stat("/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image/./usr/bin", {st_mode=S_IFDIR|0755, st_size=20, ...}) = 0 unlink("/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image/./usr/bin/urlgrabber") = 0 lgetxattr("/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image//_python2.7/./usr/bin/urlgrabber", "security.selinux", "root:object_r:portage_tmp_t:s0", 255) = 31 readlink("/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image//_python2.7/./usr/bin/urlgrabber", "../lib/python-exec/python2.7/url"..., 40) = 39 symlink("../lib/python-exec/python2.7/urlgrabber", "/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image/./usr/bin/urlgrabber") = 0 open("/proc/self/task/4063/attr/fscreate", O_RDWR|O_CLOEXEC) = 3 write(3, NULL, 0) = 0 close(3) = 0 lchown("/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image/./usr/bin/urlgrabber", 0, 0) = 0 utimensat(AT_FDCWD, "/var/tmp/portage/dev-python/urlgrabber-3.9.1-r2/image/./usr/bin/urlgrabber", {{1398350932, 637558643}, {1398350932, 637558643}}, AT_SYMLINK_NOFOLLOW) = 0 open("/proc/self/task/4063/attr/fscreate", O_RDONLY|O_CLOEXEC) = 3 read(3, "", 4095) = 0 close(3) = 0 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0} --- +++ killed by SIGSEGV +++ The full strace for cp is anexed here, as is the output of emerge urlgrabber and emerge --info.

I'm getting the same issue with other packages, gdbus-codegen for instance.
Do you get any other error messages in audit log and/or dmesg?
I've also hit it with dev-util/cppcheck, the culprit seems to be multibuild_merge_root () from multibuild.eclass it fails at this line: cp "${cp_args[@]}" "${src}"/. "${dest}"/; There seems like there was some recent changes to multibuild.eclass with relation to how copying is done http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/eclass/multibuild.eclass?view=log I've tried two of the revisions 1.14 - works fine 1.15 - fails
another package I hit it with net-wireless/aircrack-ng-1.2_beta3-r1 from dmesg: [25218.508125] cp[22756]: segfault at 0 ip 000002c5912493ea sp 0000039238150888 error 4 in libc-2.19.so[2c5911be000+1ae000] no denials either in permissive or enforcing my emerge --info: Portage 2.2.10 (hardened/linux/amd64/no-multilib/selinux, gcc-4.8.2, glibc-2.19, 3.14.3-hardened-r2 x86_64) ================================================================= System uname: Linux-3.14.3-hardened-r2-x86_64-Intel-R-_Core-TM-_i3_CPU_M_350_@_2.27GHz-with-gentoo-2.2 KiB Mem: 2996908 total, 1490712 free KiB Swap: 3145724 total, 3145160 free Timestamp of tree: Sun, 18 May 2014 00:45:01 +0000 ld GNU ld (GNU Binutils) 2.24 app-shells/bash: 4.2_p47 dev-lang/python: 2.7.6-r1, 3.3.5, 3.4.0 dev-util/cmake: 2.8.12.2-r1 dev-util/pkgconfig: 0.28-r1 sys-apps/baselayout: 2.2 sys-apps/openrc: 9999 sys-apps/sandbox: 2.6-r1 sys-devel/autoconf: 2.13, 2.69 sys-devel/automake: 1.11.6, 1.14.1 sys-devel/binutils: 2.24-r2 sys-devel/gcc: 4.8.2 sys-devel/gcc-config: 1.8 sys-devel/libtool: 2.4.2-r1 sys-devel/make: 4.0-r1 sys-kernel/linux-headers: 3.14 (virtual/os-headers) sys-libs/glibc: 2.19 Repositories: gentoo gamerlay local-overlay ACCEPT_KEYWORDS="amd64 ~amd64" ACCEPT_LICENSE="* -@EULA AdobeFlash-11.x skype-4.0.0.7-copyright" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -march=native -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/gnupg/qualified.txt" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -march=native -pipe" DISTDIR="/usr/portage/distfiles" FCFLAGS="-O2 -pipe" FEATURES="assume-digests binpkg-logs clean-logs config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync news parallel-fetch preserve-libs protect-owned sandbox selinux sesandbox sfperms splitdebug strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync webrsync-gpg xattr" FFLAGS="-O2 -pipe" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="en_US.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --omit-dir-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="/var/lib/layman/gamerlay /home/amade/overlay" SYNC="" USE="X aac acl acpi alsa amd64 berkdb bzip2 cli cracklib crypt cxx dri dvd ffmpeg flac gdbm gif gnutls gold gpg hardened iconv icu ipv6 jpeg jpeg2k justify mmx mmxext mng modules mp3 ncurses nls nptl open_perms opengl openmp pam pax_kernel pcre png qt3support readline selinux session sse sse2 sse4_1 sse4_2 ssl ssse3 svg tcpd theora threads tiff udev unicode urandom usb v4l vaapi vdpau vim-syntax x264 xattr xcb xft xinerama xpm xtpax zlib zsh-completion" ABI_X86="64" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" 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 author" 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 ublox ubx" INPUT_DEVICES="evdev keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" LINGUAS="en en_GB pl" OFFICE_IMPLEMENTATION="libreoffice" PHP_TARGETS="php5-5" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python2_7 python3_3" QEMU_SOFTMMU_TARGETS="x86_64 ppc" RUBY_TARGETS="ruby20" USERLAND="GNU" VIDEO_CARDS="nvidia" 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, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, USE_PYTHON
So as Anarchy mentioned on irc it's caused by coreutils sys-apps/coreutils-8.21 works fine sys-apps/coreutils-8.22 and sys-apps/coreutils-8.22-r1 both segfault
It has been reported and fixed upstream since. https://lists.gnu.org/archive/html/bug-coreutils/2014-01/msg00009.html I've confirmed by patching coreutils locally with the upstream patch (http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=commit;h=d718331e5) I'll attach the patch for reference as well
