this does not seem to be a gentoo-sources issue. looks as if the user has a hardware issue of some sort (probably memory). the sig 11 (seg fault) signifies a program (here gcc) accessed a memory location it was not allocated. we've had real good success with gcc-3.2.1 so, i suspect it is not a design flaw in gcc. also, the compile failed in at least 3 different places and the last was 'as' the gnu assembler, it errored on what gcc passed for it to assemble. if it was the kernel source, we would expect to fail in the same place. but, it compiles different items each time before failing... try running memtest to rule out bad memory. or look @ this article, it may be useful: http://www.bitwizard.nl/sig11/ closing as this cannot be reproduced. please reopen if you have more info.

the summary pretty much says it... after having unpacked the sources and run my menuconfig and make dep and make clean per the instructions I then went on to "make bzImage" and get a segfault: ... gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r2/include -Wall -Wstrict-prototypes -Wno-trigraphs -O3 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i686 -nostdinc -iwithprefix include -DKBUILD_BASENAME=inode -c -o inode.o inode.c In file included from /usr/src/linux-2.4.20-gentoo-r2/include/linux/sched.h:26, from inode.c:16: /usr/src/linux-2.4.20-gentoo-r2/include/linux/signal.h:114: internal error: Segmentation fault another pass segfaults at gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r2/include -Wall -Wstrict-prototypes -Wno-trigraphs -O3 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i686 -nostdinc -iwithprefix include -DKBUILD_BASENAME=do_balan -c -o do_balan.o do_balan.c do_balan.c: In function `balance_leaf': do_balan.c:1608: internal error: Segmentation fault a third pass fails with gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r2/include -Wall -Wstrict-prototypes -Wno-trigraphs -O3 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i686 -nostdinc -iwithprefix include -DKBUILD_BASENAME=binfmt_elf -c -o binfmt_elf.o binfmt_elf.c {standard input}: Assembler messages: {standard input}:2309: Error: this string may not contain '\0' make[2]: *** [binfmt_elf.o] Error 1 and it just seems as though the sucker won't build! Reproducible: Always Steps to Reproduce: 1.all I do is make :-) 2. 3. Actual Results: segfault or other error Expected Results: successfully compiled the kernel this system is a somewhat peculiar Celeron 550 with 256M of RAM; it does not have keyboard or mouse input and has a quad NIC in its one PCI interface (when the original image was built, the NIC was switched to a VGA card, and a USB keyboard was used). it is currently running an LFS build which needs some fixing anyway, so as I put in my new hard drive I am rebuilding. I don't particularly care what flavor of Linux goes on it and was pointed to Gentoo because I hear that it has build scripts so that I don't have to go through the very educational but very time-consuming LFS experience to get going :-) I am using a stage3 tarball in my mounted /tmp/A partition, which is to be the primary root on the new drive once it's the only drive in the machine. root@canal:/usr/src/linux-2.4.20-gentoo-r2# emerge info Portage 2.0.47-r3 (default-x86-1.4, gcc-3.2.1, glibc-2.3.1-r2) ================================================================= System uname: 2.4.18 i686 GENTOO_MIRRORS="http://mirrors.twobit.net/gentoo/ http://gentoo.oregonstate.edu/" CONFIG_PROTECT="/etc /var/qmail/control /usr/share/config /usr/kde/2/share/config /usr/kde/3/share/config" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" PORTDIR="/usr/portage" DISTDIR="/usr/portage/distfiles" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR_OVERLAY="" USE="x86 oss 3dnow apm arts avi gpm imlib gnome libg++ mikmod mmx motif mpeg ncurses nls oggvorbis opengl quicktime sdl svga xml2 xmms slang readline tcpd pam berkdb crypt cups curl encode ethereal gdbm gif gtk innodb java jikes jpeg kde libwww maildir mbox mozilla mysql oav pdflib perl plotutils png python qt samba sasl snmp spell ssl tetex tiff truetype X Xaw3d xv zlib" COMPILER="gcc3" CHOST="i686-pc-linux-gnu" CFLAGS="-O3 -march=i686 -mcpu=i686 -funroll-loops -ffast-math" CXXFLAGS="-O3 -march=i686 -mcpu=i686 -funroll-loops -ffast-math" ACCEPT_KEYWORDS="x86" MAKEOPTS="-j2" AUTOCLEAN="yes" SYNC="rsync://rsync.gentoo.org/gentoo-portage" FEATURES="sandbox ccache"
