I've been upgrading my system with gcc-4.3; now I'm unable to start firefox, I receive only "Segmentation fault". I tried recompiling mozilla-firefox, xulrunner and sqlite with different CFLAGS just as a test, every compilation ended fine but firefox still didn't start. I upgraded sqlite to 3.6.12 - no luck. I then removed my .mozilla configuration directory to see if there was any problem related to my profile; firefox now *starts*, but when I try to import my old bookmarks the segfault strikes back. I decided to try some kind of debugging with both situations (old and missing configuration directory) with strace but I'm unable to read anything useful; I'm attaching the logs here, bzipped because they are 1,2M and 4,8M uncompressed. The backtrace from gdb shows /usr/lib/librsvg-2.so.2 as the last recognizable point during the execution, before the segfault. Reproducible: Always Steps to Reproduce: 1. Recompile everything with gcc 4.3.2-r3 2. Try to run firefox 3. emerge --info Portage 2.1.6.7 (default/linux/x86/2008.0/desktop, gcc-4.3.2, glibc-2.8_p20080602-r1, 2.6.27-gentoo-r8 i686) ================================================================= System uname: Linux-2.6.27-gentoo-r8-i686-Genuine_Intel-R-_CPU_T2400_@_1.83GHz-with-glibc2.0 Timestamp of tree: Tue, 07 Apr 2009 16:30:17 +0000 app-shells/bash: 3.2_p39 dev-java/java-config: 2.1.7 dev-lang/python: 2.5.2-r7 dev-util/cmake: 2.6.2-r1 sys-apps/baselayout: 2.0.0 sys-apps/openrc: 0.4.3-r1 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.5, 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.18-r3 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.27-r2 ACCEPT_KEYWORDS="x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=prescott -pipe -fomit-frame-pointer -fforce-addr -mfpmath=sse" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-O2 -march=prescott -pipe -fomit-frame-pointer -fforce-addr -mfpmath=sse" DISTDIR="/usr/portage/distfiles" EMERGE_DEFAULT_OPTS="--with-bdeps y" FEATURES="distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="ftp://de-mirror.org/distro/gentoo/ http://de-mirror.org/distro/gentoo/ http://mirror.csclub.uwaterloo.ca/gentoo-distfiles/" LANG="it_IT.utf8" LC_ALL="it_IT.utf8" LDFLAGS="-Wl,-O1 -Wl,--sort-common -Wl,--as-needed" LINGUAS="it" MAKEOPTS="-j4" PKGDIR="/usr/portage/packages" PORTAGE_COMPRESS="bzip2" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/portage/local/layman/desktop-effects /usr/portage/local/layman/gnome /usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X a52 aac acpi alsa bash-completion berkdb bluetooth branding bzip2 cairo caps cddb cdparanoia cdr cli consolekit cracklib crypt cups dbus dmx dri dv dvd dvdr dvdread emboss encode evo fam ffmpeg firefox fortran gdbm gif glib gnome gnome-keyring gstreamer gtk hal iconv isdnlog java java5 java6 jpeg jpeg2k kpathsea latex lcms libnotify mad midi mikmod mmap mmx mng mp3 mpeg musepack nautilus ncurses networkmanager nls nptl nptlonly nsplugin nvidia offensive ogg opengl openmp pam pch pcre pdf perl png ppds pppd pulseaudio python quicktime readline reflection samba sdl semantic-desktop session sndfile spell spl sse sse2 sse3 ssl startup-notification svg sysfs tcpd theora threads tiff tracker truetype unicode usb vcd vorbis win32codecs wxwindows x86 xcomposite xine xinerama xml xorg xulrunner xv xvid xvmc zlib" ALSA_CARDS="hda-intel" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic auth_digest authn_anon authn_dbd authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock dbd deflate dir disk_cache env expires ext_filter file_cache filter headers ident imagemap include info log_config logio mem_cache mime mime_magic negotiation proxy proxy_ajp proxy_balancer proxy_connect proxy_http rewrite setenvif so speling status unique_id userdir usertrack vhost_alias" CAMERAS="ptp2 sierra" ELIBC="glibc" INPUT_DEVICES="keyboard mouse synaptics evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="it" USERLAND="GNU" VIDEO_CARDS="nvidia" Unset: CPPFLAGS, CTARGET, FFLAGS, INSTALL_MASK, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS

I've been able to find the right fix: reverting librsvg to 2.22.2. The weird part is that I wasn't affected by the problem since I was running gcc-4.1, I'll report this in the other bug. *** This bug has been marked as a duplicate of bug 239992 ***
