I tried to compile a tiny Eiffel program, and got an error from the compiler. Looks like it "died" rather than found an error in my source - but I COULD be wrong. If somebody would like to check this on x86 to see if it works right...? (I have no idea if this problem is Gentoo-related or if it's a bug in the upstream code. I also don't know if it's AMD64 specific or not.) Reproducible: Always Steps to Reproduce: 1. emerge smarteiffel (plus tell it to accept ~amd64) 2. Create a folder somewhere. Put 2 files in it: -----complex.e----- expanded class COMPLEX -- Class to represent complex numbers. -- this class is concrete; objects are expanded and immutable. creation {ANY} grid, polar feature {ANY} grid(re:REAL; im:REAL) is do Re := re; Im := im; Grid := false; Polar := true; end; polar(mag:REAL; arg:REAL) is require mag >= 0 do Mag := mag; Arg := arg; Grid := false; Polar := true; end; feature {COMPLEX} Re, Im, Mag, Arg : REAL; Polar, Grid: BOOLEAN; end; -- class COMPLEX -----complex.e----- -----main.e----- class MAIN creation {ANY} make feature {ANY} make is local x, y, z : COMPLEX; do create x.grid(7, 11); create y.polar(7, 11); create z.polar(-1, 2); end; end; -- class MAIN -----main.e----- 3. compile main Actual Results: bash-2.05b$ compile main Received signal 11. Eiffel program crash at run time. No trace when using option "-boost" File "main.make" not found. Error(s) during `compile_to_c'. Expected Results: Result SHOULD be a single file called a.out, plus some other temp files. Either that or - if my source is actually wrong - an explanatory message saying what's wrong. Removing the keyword "expanded" causes the program to compile normally. It hits an exception at runtime - which suggests my code is wrong. But even so, shouldn't "crash" the compiler with no meaningful error. As I say, if somebody could find out what it does on x86... bash-2.05b# emerge --info Portage 2.0.51.19 (default-linux/amd64/2005.0, gcc-3.4.3, glibc-2.3.4.20041102-r1,2.6.11-gentoo-r6 x86_64) ================================================================= System uname: 2.6.11-gentoo-r6 x86_64 AMD Athlon(tm) 64 Processor 3500+ Gentoo Base System version 1.4.16 Python: dev-lang/python-2.3.4-r1 [2.3.4 (#1, May 2 2005, 10:29:55)] ccache version 2.3 [enabled] dev-lang/python: 2.3.4-r1 sys-apps/sandbox: [Not Present] sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.5, 1.8.5-r3, 1.7.9-r1, 1.6.3, 1.4_p6, 1.9.4 sys-devel/binutils: 2.15.92.0.2-r7 sys-devel/libtool: 1.5.16 virtual/os-headers: 2.6.8.1-r4 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CFLAGS="-march=k8 -O2" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/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="-march=k8 -O2" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox strict" GENTOO_MIRRORS="http://gentoo.blueyonder.co.uk ftp://mirrors.blueyonder.co.uk/mirrors/gentoo http://www.mirrorservice.org/sites/www.ibiblio.org/gentoo/ ftp://ftp.mirrorservice.org/sites/www.ibiblio.org/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.uk.gentoo.org/gentoo-portage" USE="amd64 X acpi alsa arts bitmap-fonts bzip2 bzlib ccache cdda cddb cdr cdrom crypt curl dvd dvdr dvdread ecc encode esd fam flac font-server freetype ftp gif gpg gpm gtk2 imlib ipv6 jack java javascript jikes jp2 jpeg jpeg2k kde libwww logitech-mouse lzo lzw lzw-tiff motif mozilla mp3 mpeg msn ncurses nls ogg oggvorbis opengl pam png povray qt readline sdl speex spell ssl svg szip tcltk tcpd tetex theora threads tiff truetype truetype-fonts type1-fonts usb userlocales vorbis xml2 xpm xrandr xv zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CBUILD, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTDIR_OVERLAY *** I would like to mention that I've writted a number of small programs, all of which compile perfectly and execute as expected on AMD64.

DUH! I didn't say what VERSION of SmartEiffel, did I? :-/ dev-lang/smarteiffel-2.0_rc2
This is a bug in smarteiffel, neither gentoo, nor amd64 related.
Still a problem w/ 2.2?
Under version 2.2, the compiler now gives the error: ****** Fatal Error: Unable to find the default creation procedure for expanded type COMPLEX. An expanded type must have one unique creation procedure with no argument: the creation procedure used for automatic initialization. Please, consider to add explicitely the `default_create' procedure from ANY or some other existing procedure with no arguments. For expanded class with no creation clause, the `default_create' procedure is the one used for automatic initialization. The source lines involved by the message are the following: Line 9 column 15 in MAIN (/home/gentoo/workspace/gentoo-bugs/91601/main.e): x, y, z : COMPLEX; ^ Line 6 column 1 in COMPLEX (/home/gentoo/workspace/gentoo-bugs/91601/complex.e): creation {ANY} ^ ------ Error occurs while compiling. Compilation process aborted. Problem is fixed.
