If i start a fluid simulation with blender, blender will crashing after faw minutes with a segmantation fault. The same fluid simulation works on windows xp and arch linux. Here the blender file: http://www.2blabla.ch/stuff/untitled.blend Reproducible: Always Steps to Reproduce: 1. Start Blender 2. Run a fluid simulation with a resolution >150 Actual Results: getpid() = 2382 getpid() = 2382 getpid() = 2382 getpid() = 2382 getpid() = 2382 getpid() = 2382 getpid() = 2382 getpid() = 2382 gettimeofday({1219961399, 108051}, {4294967176, 0}) = 0 gettimeofday({1219961399, 108083}, {4294967176, 0}) = 0 gettimeofday({1219961399, 108129}, {4294967176, 0}) = 0 gettimeofday({1219961399, 108162}, {4294967176, 0}) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Portage 2.2_rc8 (default-linux/x86/2007.0, gcc-4.3.1, glibc-2.8_p20080602-r0, 2.6.26-gentoo i686) ================================================================= System uname: Linux-2.6.26-gentoo-i686-AMD_Athlon-tm-_64_X2_Dual_Core_Processor_6000+-with-glibc2.0 Timestamp of tree: Thu, 28 Aug 2008 21:06:01 +0000 ccache version 2.4 [enabled] app-shells/bash: 3.2_p39 dev-java/java-config: 1.3.7, 2.1.6-r1 dev-lang/python: 2.5.2-r7 dev-python/pycrypto: 2.0.1-r6 dev-util/ccache: 2.4-r7 sys-apps/baselayout: 2.0.0 sys-apps/openrc: 0.2.5 sys-apps/sandbox: 1.2.18.1-r3 sys-devel/autoconf: 2.13, 2.62-r1 sys-devel/automake: 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.1-r1 sys-devel/binutils: 2.18-r3 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.26 ACCEPT_KEYWORDS="x86 ~x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=k8 -O2 -msse3 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /etc/conf.d/net /etc/fstab /etc/group /etc/group- /etc/hosts /etc/passwd /etc/passwd- /etc/resolv.conf /etc/samba/smb.conf /etc/shadow /etc/shadow- /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config" 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/splash /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-march=k8 -O2 -msse3 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="candy ccache collision-protect distlocks fixpackages parallel-fetch preserve-libs sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="de_CH.UTF-8" LC_ALL="de_CH.UTF-8" LDFLAGS="" LINGUAS="de" MAKEOPTS="-j5" PKGDIR="/usr/portage/packages" 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/kde /usr/portage/local/layman/sunrise" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="3dnow 3dnowext X a52 aac aamr accessibility ace alsa apache2 arts asf aspell bzip2 cd cddb cdinstall cdparanoia cdr cdrom clamav cracklib crypt css cups curl dbus divx divx4linux dri dvd dvdr dvdread emovix encode fame ffmpeg flac foomaticdb gif gimp gzip hal icq jpeg kde lame lcms libsamplerate logrotate lua mad midi mjpeg mmx mmxext mng mp3 mpeg mplayer msn ncurses nls nptl nptlonly nsplugin ogg on-the-fly-crypt opengl pam pcre pdf php png ppds python qt qt3 qt3support qt4 rar readline samba scanner sdl smp sox spell sqlite sse sse2 sse3 ssl svg tcpd theora threads tiff unicode usb userlocales v4l v4l2 vcd videos vidix vorbis win32codecs x264 x86 xcb xcomposite xine xinerama xml xorg xv xvid zip" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1 emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks ioplug plug iec958 ladspa lfloat linear meter mulaw multi null 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" APACHE2_MPMS="worker" ELIBC="glibc" INPUT_DEVICES="mouse keyboard" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="de" USERLAND="GNU" VIDEO_CARDS="nvidia" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
Typo in the subject line; which is the other version you tried? Also, what version were you using on Arch Linux that worked properly? Finally, do you have a gcc older than 4.3 that you could try recompiling blender with? A number of apps still have compile-time issues with gcc 4.3.1, so I wouldn't be suprised if there are some with run-time issues.
I found the problem :( /tmp was to small Sorry.
