When ethereal-0.10.8 is compiled with hardened gcc-3.4.1-r1, it is very fragile. For instance, it crashes when capturing in "Update list of packets in real time mode" and the packet list gets long enough to grow a scroll bar. If compiled with vanilla gcc-3.4.1-r1, ethereal works fine. I did not experience these issues with ethereal-0.10.7 compiled with hardened gcc 3.4.3. My USE flags for ethereal are "+adns -debug +gtk +gtk2 +ipv6 +snmp +ssl" Reproducible: Always Steps to Reproduce: 1. use gcc-config to switch to hardened gcc-3.4.3-r1 ; source /etc/profile 2. emerge "=ethereal-0.10.8" 3. ethereal 4. start new capture, select "update list of packets in real time" 5. wait until the list of packets is long enough to get a scrollbar Actual Results: *** glibc detected *** free(): invalid pointer: 0x80465c40 *** Aborted Expected Results: Successful capture Portage 2.0.51-r8 (default-linux/x86/2004.3, gcc-3.4.3, glibc-2.3.4.20041102-r0, 2.6.9-gentoo-r4 i686) ================================================================= System uname: 2.6.9-gentoo-r4 i686 Intel(R) Pentium(R) 4 CPU 1.60GHz Gentoo Base System version 1.6.8 Python: dev-lang/python-2.3.4 [2.3.4 (#1, Nov 19 2004, 23:16:54)] distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] ccache version 2.3 [enabled] dev-lang/python: 2.3.4 sys-devel/autoconf: 2.59-r6, 2.13 sys-devel/automake: 1.8.5-r2, 1.5, 1.4_p6, 1.6.3, 1.7.9, 1.9.3 sys-devel/binutils: 2.15.92.0.2-r2 sys-devel/libtool: 1.5.2-r7 virtual/os-headers: 2.6.8.1-r1 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-march=pentium4 -O2 -pipe -frename-registers -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=pentium4 -O2 -pipe -frename-registers -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms" GENTOO_MIRRORS="http://mirror.datapipe.net/gentoo http://gentoo.osuosl.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.namerica.gentoo.org/gentoo-portage" USE="X aalib adns alsa apache2 apm arts avi berkdb bitmap-fonts cdr cjk crypt cscope cups doc emacs encode erandom esd f77 fam flac foomaticdb fortran gdbm gif gnome gphoto2 gpm gstreamer gtk gtk2 guile hardened imagemagick imlib ipv6 ithreads jack java jpeg junit kde ldap libg++ libwww mad mikmod mmx motif mozdevelop mozilla mozxmlterm mpeg mysql nas ncurses nls nptl odbc oggvorbis opengl oss pam pcre pdflib perl pic png postgres python qt quicktime readline samba scanner sdl slang snmp speex spell sse ssl tcltk tcpd tetex threads tiff truetype unicode x86 xface xine xinerama xml xml2 xmms xprint xrandr xv zlib"
TYPO : I meant gcc-3.4.3-r1, NOT 3.4.1 Sorry.
In addition to this bug, capture file are not correctly reconized. I have for example a GZ PCAP capture reconized as a Nokia PCAP.
It's also broken with i686-pc-linux-gnu-3.4.3-vanilla. It's perharps not exactly ethereal that was broken, because I had also this problem with Ethereal 0.10.6 compiled with Vanilla GCC.

I can't reproduce this with 0.10.11 gcc (GCC) 3.4.4 (Gentoo Hardened 3.4.4, HTB-3.4.4_pre-1.00, ssp-3.4.4-1.0, pie-8.7.8) guess it was fixed at some stage
