I think the bug here is that mcabber mixes wide and non-wide libraries in the same binary: $ lddtree /usr/bin/mcabber | egrep 'ncurses|tinfo' libtinfow.so.6 => /lib64/libtinfow.so.6 libncursesw.so.6 => /lib64/libncursesw.so.6 libtinfo.so.6 => /lib64/libtinfo.so.6 It should link consistently with libtinfow.so.6. Similar bug in gdb: https://bugs.gentoo.org/649704
Looking at mcabber's configure.ac it will have to learn to find tinfow variant: AC_CHECK_FUNC(initscr,, [ cf_ncurses="ncurses" for lib in ncursesw ncurses do AC_CHECK_LIB($lib, waddnwstr, [cf_ncurses="$lib"; cf_ncurses_unicode="yes"; break]) done AC_CHECK_LIB($cf_ncurses, initscr, [LIBS="$LIBS -l$cf_ncurses" AC_CHECK_LIB(tinfo, tgetent, [LIBS="$LIBS -ltinfo"]) <<<--- if test "$cf_ncurses" = ncursesw; then AC_CHECK_HEADERS([ncursesw/ncurses.h ncursesw/panel.h],, [AC_CHECK_HEADERS([ncurses.h panel.h],, AC_MSG_ERROR([Missing header file]))]) else AC_CHECK_HEADERS([ncurses/ncurses.h ncurses/panel.h],, [AC_CHECK_HEADERS([ncurses.h panel.h],, AC_MSG_ERROR([Missing header file]))]) fi ], [CF_CURSES_LIBS]) ])
Created attachment 595948 [details, diff] mcabber-1.1.0-tinfow.patch Try the following patch. Should be enough to drop it to /etc/portage/patches/net-im/mcabber/ and rebuild mcabber.

I've tried to apply the patch, but emerge failed on missing aclocal-1.14 (build log attached): >>> Source configured. >>> Compiling source in /var/tmp/portage/net-im/mcabber-1.1.0-r1/work/mcabber-1.1.0 ... make -j5 CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/sh /var/tmp/portage/net-im/mcabber-1.1.0-r1/work/mcabber-1.1.0/missing aclocal-1.14 -I macros /var/tmp/portage/net-im/mcabber-1.1.0-r1/work/mcabber-1.1.0/missing: line 81: aclocal-1.14: command not found WARNING: 'aclocal-1.14' is missing on your system. You should only need it if you modified 'acinclude.m4' or 'configure.ac' or m4 files included by 'configure.ac'. The 'aclocal' program is part of the GNU Automake package: <http://www.gnu.org/software/automake> It also requires GNU Autoconf, GNU m4 and Perl in order to run: <http://www.gnu.org/software/autoconf> <http://www.gnu.org/software/m4/> <http://www.perl.org/> make: *** [Makefile:413: aclocal.m4] Error 127 * ERROR: net-im/mcabber-1.1.0-r1::gentoo failed (compile phase): * emake failed * * If you need support, post the output of `emerge --info '=net-im/mcabber-1.1.0-r1::gentoo'`, * the complete build log and the output of `emerge -pqv '=net-im/mcabber-1.1.0-r1::gentoo'`. * The complete build log is located at '/var/tmp/portage/net-im/mcabber-1.1.0-r1/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/net-im/mcabber-1.1.0-r1/temp/environment'. * Working directory: '/var/tmp/portage/net-im/mcabber-1.1.0-r1/work/mcabber-1.1.0' * S: '/var/tmp/portage/net-im/mcabber-1.1.0-r1/work/mcabber-1.1.0' It seems there is a hardcoded version of automake in configure (line 2451): am__api_version='1.14' I do have only versions 1.13.4-r2 and 1.16.1-r1. So, I've installed also =sys-devel/automake-1.14.1-r2 and the emerge finished successfully then. Mcabber no longer segfaults. Also linking looks OK now: lddtree /usr/bin/mcabber | egrep 'ncurses|tinfo' libncursesw.so.6 => /lib64/libncursesw.so.6 libtinfow.so.6 => /lib64/libtinfow.so.6 Thank you! :) I am wondering why emerge of mcabber without patching worked and with patching it failed as I don't see any connection of the patch with automake version. Also, it seems this bug doesn't have anything in common with gcc version.
