Today I compiled LyX several times. At first it did not work because I had the same problem as mentioned in Bug 35729 (SIGSEGV). The I followed the instructions and removed any optimizations from my CFLAGS, so to be sure I wrote CFLAGS="" in my /etc/make.conf. Anyway, it always compiled well. But now (when compiled with CFLAGS="") when I try to run lyx I simply get a segmentationfault. How come? I had lyx running on this computer before, and it was running well. Then (for a short time) I changed to CJK-LyX and pTeX. Now I have pTeX installed, removed CJK-LyX yesterday and installed LyX today. Reproducible: Always Steps to Reproduce: 1. emerge lyx (with CFLAGS="") 2. lyx 3. Actual Results: Segmentationfault (in German: Speicherzugriffsfehler) LyX does not start. Expected Results: LyX should start. io ~ # emerge info Portage 2.0.51_rc1 (gcc34-x86-2004.2, gcc-3.3.4, glibc-2.3.4.20040808-r0, 2.6.8-gentoo-r4 i686) ================================================================= System uname: 2.6.8-gentoo-r4 i686 Intel(R) Pentium(R) M processor 1500MHz Gentoo Base System version 1.5.3 distcc 2.17 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] ccache version 2.3 [disabled] Autoconf: sys-devel/autoconf-2.59-r4 Automake: sys-devel/automake-1.8.5-r1 Binutils: sys-devel/binutils-2.15.90.0.1.1-r3 Headers: sys-kernel/linux26-headers-2.6.8.1 Libtools: sys-devel/libtool-1.5.2-r5 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CFLAGS="" CHOST="i686-pc-linux-gnu" COMPILER="" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.3/share/config:/usr/kde/3.3/env:/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="" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs nostrip sandbox" GENTOO_MIRRORS="ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/gentoo http://ftp.uni-erlangen.de/pub/mirrors/gentoo http://ftp.easynet.nl/mirror/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X aalib acpi alsa anthy apm arts avi berkdb bitmap-fonts bonobo canna cdr cjk crypt cups directfb dvd dvdr encode esd fbcon flac foomaticdb freewnn gdbm ggi gif gimpprint gnome gphoto2 gpm gtk gtk2 gtkhtml guile imlib ipv6 java jpeg kde ldap libg++ libwww lzw-tiff mad mikmod mmx motif mozcalendar mozilla moznocompose moznoirc mozsvg mpeg ncurses nls nptl oggvorbis opengl oss pam pda pdflib perl png ppds python qt quicktime readline ruby samba scanner sdl skk slang spell sse sse2 ssl svg svga tcltk tcpd tetex tiff truetype unicode usb wifi x86 xml xml2 xmms xprint xv xvid zlib linguas_de linguas_ja" ----------------------------------------------------- io ~ # emerge ptex xdvik lyx -pv These are the packages that I would merge, in order: Calculating dependencies ...done!

i tried compiling it on another machine, made a package of it and installed the package on this machine.. works! so maybe the problem is gcc? i still have no idea. but, wait! i compiled it on another machine, but compiled it with distcc, so i used this and another system for compiling. and it works here without problems (yet). on this machine i use sys-devel/gcc-3.3.4-r1 on the other machine it's 3.3.2.
I suppose it's not reproduceable.... If it persists in lyx-1.3.5 and reproduceable with specific version of gcc, please reopen. I'll try that version of gcc and block if it doesn't work. (at least lyx-1.3.5 compiles fine with gcc-3.4.1 and gcc-3.3.4 on my machine) Thanks in advance.
Any news on this? john@newkid ~ $ lyx lyx: SIGSEGV signal caught Sorry, you have found a bug in LyX.
