I've compiled bash with "-fsanitize=address", next I did reboot. Now I'm getting flood messages as below: ==69== AddressSanitizer CHECK failed: /var/tmp/portage/sys-devel/gcc-4.8.3/work/gcc-4.8.3/libsanitizer/sanitizer_common/sanitizer_linux.cc:309 "((proc_self_maps_.len)) > ((0))" (0x0, 0x0) ==69== AddressSanitizer CHECK failed: /var/tmp/portage/sys-devel/gcc-4.8.3/work/gcc-4.8.3/libsanitizer/sanitizer_common/sanitizer_linux.cc:309 "((proc_self_maps[ 43.228856] sh[69]: segfault at 7fff67f27e28 ip 00007f1f28a0176c sp 00007fff67f27e30 error 6_.len)) > ((0))" (0x0, 0x0) ==69== AddressSanitizer CHECK failed: /var/tmp/portage/sys-devel/gcc-4.8.3/work/gcc-4.8.3/libsanitizer/sanitizer_common/sanitizer_linux.cc:309 "((proc_self_maps_.len)) > ((0))" (0x0, 0x0) ==69== AddressSanitizer CHECK failed: /var/tmp/portage/sys-devel/gcc-4.8.3/work/gcc-4.8.3/libsanitizer/sanitizer_common/sanitizer_linux.cc:309 "((proc_self_maps_.len)) > ((0))" (0x0, 0x0) in libasan.so.0.0.0[7f1f289ef000+29000] Now I can't even login du te bash/sh refuses to cooperate with me:) So I'm wondering if it is bug in sanitizer or it is my fault because I've made default shell unusable? Reproducible: Always
Please post your `emerge --info app-shells/bash' output in a comment.
I recompiled bash with -fsanitize=address, I could open new window in tmux so I assume that bash was working, but after reboot again I have problems. emerge --info is below. # emerge --info bash Portage 2.2.8-r2 (hardened/linux/amd64, gcc-4.8.3, glibc-2.19-r1, 3.16.5-gentoo x86_64) ================================================================= System Settings ================================================================= System uname: Linux-3.16.5-gentoo-x86_64-Intel_Xeon_E312xx_-Sandy_Bridge-with-gentoo-2.2 KiB Mem: 798916 total, 347296 free KiB Swap: 511996 total, 511996 free Timestamp of tree: Fri, 24 Oct 2014 04:15:01 +0000 ld GNU gold (Gentoo 2.23.2 p1.0 2.23.2) 1.11 ccache version 3.1.9 [enabled] app-shells/bash: 4.2_p53 dev-lang/perl: 5.18.2-r2 dev-lang/python: 2.7.7, 3.3.5-r1, 3.4.1 dev-util/ccache: 3.1.9-r3 dev-util/pkgconfig: 0.28-r1 sys-apps/baselayout: 2.2 sys-apps/openrc: 0.12.4 sys-apps/sandbox: 2.6-r1 sys-devel/autoconf: 2.69 sys-devel/automake: 1.13.4 sys-devel/binutils: 2.23.2 sys-devel/gcc: 4.7.3-r1, 4.8.3 sys-devel/gcc-config: 1.7.3 sys-devel/libtool: 2.4.2-r1 sys-devel/make: 4.0-r1 sys-kernel/linux-headers: 3.13 (virtual/os-headers) sys-libs/glibc: 2.19-r1 Repositories: gentoo ACCEPT_KEYWORDS="amd64" ACCEPT_LICENSE="* -@EULA" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -march=core2 -mtune=native -fsanitize=address" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -pipe -march=core2 -mtune=native -fsanitize=address" DISTDIR="/usr/portage/distfiles" FCFLAGS="-O2 -pipe" FEATURES="assume-digests binpkg-logs ccache collision-protect config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync news parallel-fetch preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr" FFLAGS="-O2 -pipe" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="pl_PL.utf8" LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--sort-common" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_EXTRA_OPTS="-O" 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="" SYNC="" USE="acl acpi amd64 bash-completion caps cli cracklib crypt cxx dri hardened iconv ipv6 justify mmx mmxext modules multilib ncurses nls nptl openmp pax_kernel pcre readline session sse sse2 sse3 ssse3 threads unicode urandom vim-syntax xattr xtpax" 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="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" OFFICE_IMPLEMENTATION="libreoffice" PHP_TARGETS="php5-5" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python3_3" RUBY_TARGETS="ruby19 ruby20" USERLAND="GNU" VIDEO_CARDS="fbdev glint intel mach64 mga nouveau nv r128 radeon savage sis tdfx trident vesa via vmware 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" USE_PYTHON="2.7 3.3" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS ================================================================= Package Settings ================================================================= app-shells/bash-4.2_p53 was built with the following: USE="net nls (readline) -afs -bashlogger -examples -mem-scramble -plugins -vanilla" ABI_X86="64"
