While compiling the following trivial file, the gfortran compiler reports fif.f: In function 'fif': fif.f:17: error: unrecognizable insn: (insn 90 46 48 5 (set (reg:DF 8 st [81]) (const_double:SF 0 [0x0] 0.0 [0x0.0p+0])) -1 (nil) (nil)) fif.f:17: internal compiler error: in extract_insn, at recog.c:2084 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugs.gentoo.org/> for instructions. The file follows (there's also a real*8 version which surprisingly compiles well) C*3 FIF C+ C Function for polar cohordinate Fi mod pigrec C REAL FUNCTION FIF(Y,X) REAL*8 X,Y C C-- C 13-Feb-1991 C----------------------------------------------------------------------- IF (X*X+Y*Y.EQ.0.)

emerge --info, please.
The bug appeared when I tried to compile the above file with the options gfortran -ff2c -c Sorry, I'm not very familiar with this bug report stuff. (I'll add that I filed a bug only because the compiler asked me to. I don't really need to compile the above file which is part of a huge library which for the rest compiles almost fine). emerge --info follows: Gentoo Base System version 1.12.5 Portage 2.1.1-r1 (default-linux/x86/2006.1, gcc-4.1.1, glibc-2.4-r3, 2.6.17-gentoo-r8 i686) ================================================================= System uname: 2.6.17-gentoo-r8 i686 Intel(R) Pentium(R) 4 Mobile CPU 1.80GHz Last Sync: Thu, 09 Nov 2006 17:00:01 +0000 app-admin/eselect-compiler: [Not Present] dev-java/java-config: 2.0.30 dev-lang/python: 2.4.3-r4 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: [Not Present] dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.16.1-r3 sys-devel/gcc-config: 1.3.13-r3 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.17-r1 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=i686 -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/X11/xkb /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/" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/gconf /etc/java-config/vms/ /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-O2 -march=i686 -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude='/distfiles' --exclude='/local' --exclude='/packages'" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X alsa berkdb bitmap-fonts cdparanoia cli cracklib crypt cups directfb divx4linux dlloader dri dvd dvdread elibc_glibc encode f77 fame fftw fortran ftp g77 gdbm gif gnome gpm gtk iconv ifc input_devices_evdev input_devices_keyboard input_devices_mouse isdnlog jpeg kerberos kernel_linux libg++ mad mbox mmx mmx2 motif mozilla mp3 mpeg ncurses nls nptl nptlonly nsplugin nvidia ogg oggvorbis opengl oss pam pcmcia pcre perl png ppds pppd python quicktime readline reflection session spl ssl tcltk tcpd tetex truetype-fonts type1-fonts udev unicode usb userland_GNU video_cards_nv video_cards_nvidia video_cards_vesa vorbis win win32codecs xemacs xine xinerama xinetd xorg xv xvid xvmc zlib" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
