gcc-3.4.4 ICEs while compiling the file 'numeric.c' in libperl-5.8.5 with the CFLAG '-O1' set. Without this flag, it compiles the whole package fine. Reproducible: Always Steps to Reproduce: 1. emerge =sys-devel/gcc-3.4.4 2. set CFLAGS="-O1" 3. emerge =sys-devel/libperl-5.8.5 4. set CFLAGS="" 5. emerge =sys-devel/libperl-5.8.5 Actual Results: In step 3, gcc ICEs in numeric.c : "`sh cflags "optimize='-pipe -O1'" numeric.o` -fPIC numeric.c CCCMD = i686-pc-linux-gnu-gcc -DPERL_CORE -c -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -pipe -O1 -Wall numeric.c: In function `S_mulexp10': numeric.c:787: internal compiler error: in try_split, at emit-rtl.c:3343" In step 5, the file compiles fine. Expected Results: Compile both ;) - libperl compiles fine with gcc-3.3.5-r1 with -O1. - it still ICEs with gcc vanilla profile on gcc-3.4.4 with -O1 emerge info : Portage 2.0.51.19 (hardened/x86/2.6, gcc-3.4.4, glibc-2.3.4.20041102-r1, 2.6.12-rc4-nitro1-k1 i686) ================================================================= System uname: 2.6.12-rc4-nitro1-k1 i686 Intel(R) Pentium(R) M processor 1.70GHz Gentoo Base System version 1.6.12 Python: dev-lang/python-2.3.5 [2.3.5 (#1, May 1 2005, 03:23:48)] ccache version 2.3 [enabled] dev-lang/python: 2.3.5 sys-apps/sandbox: [Not Present] sys-devel/autoconf: 2.59-r6, 2.13 sys-devel/automake: 1.7.9-r1, 1.8.5-r3, 1.5, 1.4_p6, 1.6.3, 1.9.5 sys-devel/binutils: 2.15.92.0.2-r7 sys-devel/libtool: 1.5.16 virtual/os-headers: 2.6.8.1-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-pipe -O2 -fomit-frame-pointer -fprefetch-loop-arrays -momit-leaf-frame-pointer -march=pentium-m -fweb " CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /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="-pipe -O2 -fomit-frame-pointer -fprefetch-loop-arrays -momit-leaf-frame-pointer -march=pentium-m -fweb " DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks nostrip sandbox sfperms strict" GENTOO_MIRRORS="ftp://cs.ubishops.ca/pub/gentoo" LANG="fr_FR.UTF-8" LC_ALL="fr_FR.UTF-8" LDFLAGS="-Wl,-O1" LINGUAS="fr" MAKEOPTS="-j1" PKGDIR="/usr/portage//packages/x86/" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage/" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X aac acpi alsa apache2 arts artswrappersuid avi bash-completion berkdb bzip2 cddb cdio cdparanoia cdr crypt curl dga directfb dlloader dvd dvdread exiscan exiscan-acl fam fbcon ffmpeg flac fortran freetype gd gdbm gif gstreamer gtk2 hal hardened icq imagemagick imlib jack jack-tmpfs java jpeg jpeg2k junit kde kdeenablefinal libwww lzw-tiff mad matroska mmap mmx mozilla moznocompose moznoirc moznomail mozsvg mp3 mpeg msn mysql ncurses network nls nomotif nptl ogg oggvorbis opengl openntpd pam pdflib perl pic plotutils png prelink python qt quicktime readline real rtc shaper speex spell sqlite sse sse2 ssl stream svga sysfs tcpd tetex tiff truetype unicode userlocales vorbis win32codecs x86 xine xml2 xmms xrandr xv xvid zeroconf zlib linguas_fr userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CBUILD, CTARGET

I saw this was assigned to perl devs, but it's a GCC bug : I just discovered that gcc ICEs exactly at the same place (in emit-rtl.c:3343) while compiling =media-libs/libsndfile-1.0.11 with -O1 but is fine with no optimization.
