The ebuild appears to react unpredictably to various choices of CFLAGS. Reproducible: Always Attempting to re-emerge dev-libs/icu-4.4-r1 also fails, although it had been compiled as recently as a few weeks ago without issue. I am not certain what changed to cause dev-libs/icu's compilation to fail. A regular "emerge icu" fails. If I modify the command to be: CFLAGS="-O3 -pipe -march=core2 -msse4.1 -mcx16 -msahf --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=6144 -ftree-loop-linear -fgcse-sm -fgcse-las -ftree-loop-im -ftree-loop-ivcanon -fivopts -frename-registers -fweb" CXXFLAGS=${CFLAGS} CPPFLAGS=${CFLAGS} emerge icu It will also fail. However, this is when things become interesting. "-march=core2 -msse4.1 -mcx16 -msahf --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=6144" is roughly the equivalent of "-march=native". Substituting "-march=native" works: CFLAGS="-O3 -pipe -march=native -ftree-loop-linear -fgcse-sm -fgcse-las -ftree-loop-im -ftree-loop-ivcanon -fivopts -frename-registers -fweb" CXXFLAGS=${CFLAGS} CPPFLAGS=${CFLAGS} emerge icu That would seem to indicate that those flags are a problem, but if I were to leave the flags that are equivalent to "-march=native" in that command and remove the other flags, it also works: CFLAGS="-O3 -pipe -march=core2 -msse4.1 -mcx16 -msahf --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=6144" CXXFLAGS=${CFLAGS} CPPFLAGS=${CFLAGS} emerge icu Emerging ICU has always been problematic on my system, so I wanted to figure out why it was failing, but I am at a loss to explain these results. #

Missing build log.
Created attachment 230037 [details] Build log from "emerge icu" Here is a build log.
Same problem here. This is the weirdiest error I ever seen. If fails with the following CFLAGS: CFLAGS="-march=athlon-xp --param l1-cache-line-size=64 --param l1-cache-size=64 --param l2-cache-size=512 -funswitch-loops -fpredictive-commoning -fgcse-after-reload -fomit-frame-pointer -ftree-loop-linear -floop-strip-mine" Note 1: This is minimal CFLAGS required to reproduce a problem. With *any* single flag of these above removed it compiles. Note 2: CXXFLAGS are unaffected and defaults from make.conf were used. $ emerge --info Portage 2.2_rc67 (default/linux/x86/10.0, gcc-4.4.3, glibc-2.11.1-r0, 2.6.33.3-yoruichi i686)

Can confirm this bug. I've triggerd it with the following CFLAGS: CFLAGS="-march=k8-sse3 -O2 -mfpmath=sse -fweb -ftracer -funswitch-loops -fpredictive-commoning -fgcse-after-reload -ftree-vectorize -fomit-frame-pointer -ftree-loop-distribution -ftree-loop-im -fvect-cost-model -pipe" CXXFLAGS="${CFLAGS}" Removing one of this flags makes icu compile fine. Exceptions are -ftracer and -pipe. They must be removed together to make icu compile. I don't have a clue what's happening there, but -pipe is related to this. And it's not a case of parallel make problem. Have tested it with MAKEOPTS="-j1". emerge --info Portage 2.1.8.3 (default/linux/x86/10.0, gcc-4.4.3, glibc-2.11-r1, 2.6.33 i686) ================================================================= System uname: Linux-2.6.33-i686-AMD_Opteron-tm-_Processor_252-with-gentoo-2.0.1 Timestamp of tree: Tue, 04 May 2010 10:00:01 +0000 app-shells/bash: 4.1_p5 dev-java/java-config: 2.1.11 dev-lang/python: 2.6.5-r2, 3.1.2-r3 dev-util/cmake: 2.8.1-r1 sys-apps/baselayout: 2.0.1 sys-apps/openrc: 0.6.1-r1 sys-apps/sandbox: 2.2 sys-devel/autoconf: 2.13, 2.65 sys-devel/automake: 1.11.1 sys-devel/binutils: 2.20.1 sys-devel/gcc: 4.4.3-r2 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6b virtual/os-headers: 2.6.33 ACCEPT_KEYWORDS="x86 ~x86" ACCEPT_LICENSE="* -@EULA" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=k8-sse3 -O2 -mfpmath=sse -fweb -ftracer -funswitch-loops -fpredictive-commoning -fgcse-after-reload -ftree-vectorize -fomit-frame-pointer -ftree-loop-distribution -ftree-loop-im -fvect-cost-model -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/X11/xkb /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/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c" CXXFLAGS="-march=k8-sse3 -O2 -mfpmath=sse -fweb -ftracer -funswitch-loops -fpredictive-commoning -fgcse-after-reload -ftree-vectorize -fomit-frame-pointer -ftree-loop-distribution -ftree-loop-im -fvect-cost-model -pipe" DISTDIR="/usr/portage/distfiles" EMERGE_DEFAULT_OPTS="--with-bdeps=y" FEATURES="assume-digests distlocks fixpackages news parallel-fetch protect-owned sandbox sfperms strict unmerge-logs unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="de_DE.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--sort-common -Wl,-z,combreloc" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" 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="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X acl alsa berkdb bzip2 cairo cli cracklib crypt cups cvs cxx dbus dri fortran gdbm git gpm graphite hal iconv ipv6 java mmx modules mudflap ncurses nls nptl nptlonly nsplugin openmp pam pcre perl pppd python readline reflection session spl sqlite sqlite3 sse sse2 ssl subversion svg sysfs tcpd unicode x86 xcb 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" ELIBC="glibc" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="fbdev glint intel mach64 mga neomagic nv r128 radeon savage sis tdfx trident vesa via vmware voodoo" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, FFLAGS, INSTALL_MASK, LC_ALL, LINGUAS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
Why is this bug assigned to php-bugs?
Perhaps we should also ask why it is still marked "RESOLVED NEEDINFO". I am reopening it because apparently, I have the ability to do that as the original poster. I had hoped that one of Gentoo's developers would do this, but I am afraid that this bug will never be seen by them again should it be left this way.
Someone offline was distracting me, which kept me from reopening the bug with my previous comment. This one should reopen it.
Try not ricing your C/XXFLAGS.
(In reply to comment #8) > Try not ricing your C/XXFLAGS. > The system I have which has issues with this bug is a virtual machine that was intended to be used to find these kinds of bugs. Your suggestion is the equivalent of suggesting that no one ever do any Quality Assurance testing because trying to proactively discover bugs before less technical people encounter them is cheating. If you want that kind of experience, I suggest you try Ubuntu.
The problem is at pkgdata.cpp:488: ... #define SMALL_BUFFER_MAX_SIZE 512 ... static int runCommand(const char* command, UBool specialHandling) { char cmd[SMALL_BUFFER_MAX_SIZE]; ... } else { normal_command_mode: sprintf(cmd, "%s", command); // line 488 } ... When the supplied command line ("x86_64-pc-linux-gnu-gcc -D_REENTRANT -O2 -pipe ...") is too long, buffer overflow occurs. (I have to say, it surprises me that sprintf/strcat is used everywhere in the code, without any bounds checking)
