When emerging app-text/wdiff, the process hangs in the "configure" script. The blocking "conftest" process must be killed, to allow the compilation to go on. Reproducible: Always Steps to Reproduce: emerge app-text/wdiff Actual Results: [...] checking whether mbrtowc returns 0 when parsing a NUL character... guessing yes checking whether mbrtowc handles incomplete characters... (cached) guessing yes checking whether mbrtowc works as well as mbtowc... (cached) guessing yes checking whether YESEXPR works... yes checking whether readlink signature is correct... yes checking whether readlink handles trailing slash correctly... yes checking for working re_compile_pattern... And the process hangs here. Killing the "conftest" process from another shell allows the compilation to continue. Expected Results: The emerge process should not stop. # emerge --info Portage 2.2.7 (default/linux/x86/13.0, gcc-4.6.3, glibc-2.17, 3.10.17-gentoo i686) ================================================================= System uname: Linux-3.10.17-gentoo-i686-Intel-R-_Atom-TM-_CPU_N2600_@_1.60GHz-with-gentoo-2.2 KiB Mem: 2057880 total, 404296 free KiB Swap: 4194300 total, 4194208 free Timestamp of tree: Sat, 04 Jan 2014 01:45:01 +0000 ld GNU ld (GNU Binutils) 2.23.2 app-shells/bash: 4.2_p45 dev-lang/python: 2.7.5-r3, 3.2.5-r3, 3.3.2-r2 dev-util/cmake: 2.8.10.2-r2 dev-util/pkgconfig: 0.28 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: 1.11.6, 1.12.6, 1.13.4 sys-devel/binutils: 2.23.2 sys-devel/gcc: 4.6.3, 4.7.3-r1 sys-devel/gcc-config: 1.7.3 sys-devel/libtool: 2.4.2 sys-devel/make: 3.82-r4 sys-kernel/linux-headers: 3.9 (virtual/os-headers) sys-libs/glibc: 2.17 Repositories: gentoo ACCEPT_KEYWORDS="x86" ACCEPT_LICENSE="* -@EULA" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=atom -pipe" CHOST="i686-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=atom -pipe" DISTDIR="/usr/portage/distfiles" FCFLAGS="-O2 -march=i686 -pipe" FEATURES="assume-digests binpkg-logs 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" FFLAGS="-O2 -march=i686 -pipe" GENTOO_MIRRORS="http://de-mirror.org/gentoo/ http://mirror.switch.ch/ftp/mirror/gentoo/" LANG="en_US.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" 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="" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="acl acpi berkdb bzip2 cli cracklib crypt cups cxx dri emacs fortran games gdbm gpg iconv imap ipv6 mbox modules mudflap ncurses nls nptl openmp pam pcre perl pop posix ppds python readline samba sasl session smime sockets ssl symlink tcltk tcpd threads unicode usb wifi x86 xinetd xml zlib" ABI_X86="32" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1 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="python2_7 python3_3" RUBY_TARGETS="ruby19 ruby18" 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" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LC_ALL, MAKEOPTS, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, USE_PYTHON

Hello Jeroen, thank you for taking care of this bug. IMHO, however, this is not related in any way to NVIDIA drivers: - among the installed ebuilds, none contains the word "nvidia"; - there is no "nvidia.ko" module loaded; - none of the peripherals listed by lspci seem to be made by NVIDIA. I hope this helps. :-) I am not touching the status of this bug, I am leaving this decision to you. Please let me know if I can provide any more information.
Can you tell us what you do have? - Which video card? - Which driver? - What is the state of the hung process? - Can you reproduce the sigprocmask results from bug #487558? - What do you see if you strace and ltrace the hung process? - Can you try to see if you can get a backtrace of conftest? (*) - When did you started experiencing this? - Can we see enough of the last lines of `genlop -l` or `qlop -l`? (genlop is from app-portage/genlop, qlop from app-portage/portage-utils) Thank you in advance. (*) https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
Can you also attach your `dmesg` and kernel .config in addition to the above?
Hello, after I rebooted (kernel updated to version 3.10.25) the problem disappeared. I tried to revert to kernel 3.10.17 but it had no effect. I am sorry, I cannot reproduce this problem myself anymore. I will check my RAM later... To answer Tom's questions: this is a headless box, powered by an Atom processor. No X installed. Sorry for the noise and thank you for following this report.
