I can't reproduce this bug. Are you able to reproduce this bug with dev-lang/python-2.6.4? Sorry, this *is* with 2.6.4: Portage 2.1.7.9 (default/linux/x86/10.0, gcc-4.4.2-asneeded, glibc-2.11-r0, 2.6.32-rc8 i686) ================================================================= System uname: Linux-2.6.32-rc8-i686-Quad-Core_AMD_Opteron-tm-_Processor_2350-with-gentoo-2.0.1 Timestamp of tree: Tue, 01 Dec 2009 11:00:01 +0000 distcc 3.1 i686-pc-linux-gnu [disabled] ccache version 2.4 [enabled] app-shells/bash: 4.0_p35 dev-java/java-config: 1.3.7-r1, 2.1.9-r1 dev-lang/python: 2.6.4, 3.1.1-r1 dev-python/pycrypto: 2.0.1-r8 dev-util/ccache: 2.4-r8 dev-util/cmake: 2.6.4-r2 sys-apps/baselayout: 2.0.1 sys-apps/openrc: 0.5.2-r2 sys-apps/sandbox: 2.1 sys-devel/autoconf: 2.13, 2.65 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2, 1.11 sys-devel/binutils: 2.20 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.30-r1 ACCEPT_KEYWORDS="x86 ~x86" ACCEPT_LICENSE="*" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /opt/openfire/resources/security/ /opt/openjms/config /usr/lib/ccs/conf /usr/lib/fax /usr/share/X11/xkb /usr/share/bufrtables /usr/share/config /usr/share/qpsmtpd/plugins /var/bind /var/lib/hsqldb /var/phxd /var/spool/fax/etc /var/spool/torque /var/vpopmail/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/eselect/postgresql /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-O2 -pipe" DISTDIR="/var/cache/distfiles" FEATURES="assume-digests ccache distlocks fixpackages news parallel-fetch protect-owned sandbox sfperms split-log strict test test-fail-continue unmerge-orphans userfetch" GENTOO_MIRRORS="http://ftp.uni-erlangen.de/pub/mirrors/gentoo" INSTALL_MASK=" /usr/share/doc /usr/share/info" LDFLAGS="-Wl,-O1" MAKEOPTS="-j14" PKGDIR="/var/spool/portage/packages" PORTAGE_COMPRESS="" PORTAGE_CONFIGROOT="/" 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="/var/cache/portage/tree-tinderbox" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="acl berkdb bzip2 cli cracklib crypt cups dri fortran gdbm gpm iconv ipv6 java5 java6 modules mudflap ncurses nls nostatic nptl nptlonly openmp pam pcre perl pppd python qt3support readline reflection ruby session spl ssl sysfs tcpd unicode x86 xorg zlib" 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 iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon 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 deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias auth_digest" ELIBC="glibc" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" RUBY_TARGETS="ruby18" USERLAND="GNU" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, LANG, LC_ALL, LINGUAS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY I understand you cannot reproduce, but give me a clue where to look for the possibility? I have tried changing locales already. [ebuild R ] dev-lang/python-2.6.4 USE="berkdb gdbm ipv6 ncurses readline sqlite ssl threads tk xml -build -doc -examples -ucs2 -wininst" 0 kB [ebuild R ] dev-lang/python-3.1.1-r1 USE="gdbm ipv6 ncurses readline sqlite ssl threads tk xml -build -doc -examples -ucs2 -wininst" 9 kB Maybe try with lower optimizations (e.g. -O1). (Tests with Python 3 are already disabled due to Python issue 7173.) That seems to do the trick, strict aliasing bug? I don't know. -O2 and higher are already replaced with -O1 on amd64, so maybe it should be extended to x86... In case of dev-python/cython-0.12, I can't reproduce test failure with unfiltered -O3 on amd64. This bug seems to occur only with GCC 4.4.2, but not GCC 4.3.4. (In reply to comment #10) > This bug seems to occur only with GCC 4.4.2, but not GCC 4.3.4. > You're right. You need GCC 4.4.2 and CFLAGS=-O3 to make the cython testsuite fail.

Why not open a upstream bug for this, and then append-flags -fno-strict-aliasing and be done with it? Only saying because this is one of the last bugs in gcc-4.4 porting tracker... The ebuild now appends -fno-strict-aliasing. |
