As it is said in the summary mp3c-0.31 (but also mp3c-0.29 had the same problem) segfaults in the main screen whenewer one presses the enter key to modify track data (author, title, whatever). This has started happening after my system was converted to gcc-4.1 and glibc-2.4. If I tune down my CFLAGS to -O2 the segfault is delayed and it happens after the track data is modified and you try to go back to the main screen. # emerge --info Portage 2.1.1-r1 (default-linux/amd64/2006.1/desktop, gcc-4.1.1, glibc-2.4-r4, 2.6.17-gentoo-r8 x86_64) ================================================================= System uname: 2.6.17-gentoo-r8 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4600+ Gentoo Base System version 1.12.6 Last Sync: Tue, 07 Nov 2006 09:00:01 +0000 distcc 2.18.3 x86_64-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] ccache version 2.3 [enabled] app-admin/eselect-compiler: [Not Present] dev-java/java-config: 1.3.7, 2.0.30 dev-lang/python: 2.4.3-r4 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.3 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.60 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.16.1-r3 sys-devel/gcc-config: 1.3.13-r4 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=k8 -O3 -pipe -fomit-frame-pointer" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/gconf /etc/java-config/vms/ /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-march=k8 -O3 -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache collision-protect distcc distlocks fixpackages metadata-transfer sandbox sfperms strict test userfetch userpriv usersandbox" GENTOO_MIRRORS="http://gentoo.ngi.it http://gentoo.intergenia.de http://ftp-stud.fht-esslingen.de/pub/Mirrors/gentoo/ http://ftp.ntua.gr/pub/linux/gentoo/" LANG="it_IT.UTF-8" LC_ALL="it_IT.UTF-8" LINGUAS="it" MAKEOPTS="-j11" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude='/distfiles' --exclude='/local' --exclude='/packages'" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64 X Xaw3d a52 aalib acpi alsa arts audiofile bash-completion berkdb bitmap-fonts bzip2 cairo caps cdparanoia cdr cli cracklib crypt cups curl dbus dga dio dlloader dri dvd dvdr dvdread elibc_glibc emboss emul-linux-x86 encode exif expat fam fbcon ffmpeg fftw firefox flac foomaticdb fortran ftp gd ggi gif glut gmp gnutls gphoto2 gpm gstreamer gtk2 hal iconv idn ieee1394 imagemagick imlib input_devices_evdev input_devices_keyboard input_devices_mouse isdnlog java javascript jbig jikes jpeg jpeg2k kde kdeenablefinal kernel_linux lcms libcaca libg++ linguas_it lm_sensors lua mad maildir matroska memlimit mikmod mime mmap mng motif mozilla mp3 mpeg mpi ncurses nls nptl nptlonly nsplugin offensive ogg openal opengl oss pam pcre pdf perl png posix ppds pppd python qt3 quicktime readline recode reflection samba sasl sdl session sharedmem shorten sndfile sockets sox speex spell spl ssl svg symlink sysvipc tcl tcltk tcpd theora threads tidy tiff tk truetype truetype-fonts type1-fonts udev unicode usb userland_GNU vcd video_cards_radeon vorbis wmf xine xml xorg xosd xpm xv xvid zlib" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LDFLAGS, PORTAGE_RSYNC_EXTRA_OPTS
A quick note to add that I just read in the program documentation that segfaults may also be related to ncurses.
Please, reopen with a backtrace. Thanks. http://www.gentoo.org/proj/en/qa/backtraces.xml
After recompiling mp3c, ncurses and glibc with FEATURES="nostrip" CFLAGS="-march=k8 -O2 -pipe" CXXFLAGS="-march=k8 -O2 -pipe" USE="debug trace -glibc-omitfp" I still get: (gdb) bt full #0 0x000000000041f220 in select_field_box () No symbol table info available. #1 0x0000000000414bcf in alter_track_infos_menu () No symbol table info available. #2 0x00000000004101f8 in main_loop () No symbol table info available. #3 0x000000000041359f in main () No symbol table info available.

This sounds to me like an abi incompatibility, did you follow http://www.gentoo.org/doc/en/gcc-upgrading.xml after migrating to gcc 4.1.1 ? (ie, emerge -e system && emerge -e world after switching to gcc 4.1.1 ) I can't reproduce it here and it does not seem that your cflags are faulty. I'm ~amd64 so I may not have the same libs as you, that's just to be sure before trying several combinations of libs.

Besides it also happens on a native gcc-4.1.1 system. :(
Ok, I'm now able to reproduce it by setting my locales to italian. While I'm trying to fix it, if you're blocked by this bug, it should work by setting your locales to C, something like "LC_ALL=C mp3c" to start mp3c.
I've added a patch to 0.29-r1 and 0.31-r1, and also reported upstream. This was due to a buffer overflow because the translated string was longer than the size of the buffer. Please confirm that 0.29-r1 is working as expected then I'll ask for it to be stabilized.

Thank you very much for your help Paolo, without your backtrace it would have been a harass to track this bug. @Arches, please stabilize media-sound/mp3c-0.29-r1, 0.29 segfaults when, for example, using italian locales. @ppc: You don't have 0.29 stable, but maybe you'll be interested in having 0.29-r1 stable since you're the only keyworded arch that does not have a stable version of mp3c. About 0.31-r1, it'll have to wait a little bit, at least one month, before reaching stable because I bumped it some days ago. Please file a bug when it'll have been kept long enough in ~arch without bug to stabilize 0.31-r1.
