So this is a compiler or system header error?
Anybody examined the differences in code generated with native compiler
and crosscompiler?
Is there some code difference or are wrong kernel headers pulled from
i386 resulting in invalid syscalls?

Title:
qemu-i386 user mode on ARMv5 host fails (bash: fork: Invalid argument)
Status in QEMU:
New
Bug description:
Good time of day everybody,
I have been trying to make usermode qemu on ARM with plugapps
(archlinux) with archlinux i386 chroot to work.
1. I installed arch linux in a virtuabox and created a chroot for it with
mkarchroot. Transferred it to my pogo plug into /i386/
2. I comiled qemu-i386 static and put it into /i386/usr/bin/
./configure --static --disable-blobs --disable-system
--target-list=i386-linux-user
make
3. I also compiled linux kernel 2.6.38 with CONFIG_BINFMT_MISC=y and
installed it.
uname -a
Linux Plugbox 2.6.38 #4 PREEMPT Fri Mar 18 22:19:10 CDT 2011 armv5tel
Feroceon 88FR131 rev 1 (v5l) Marvell SheevaPlug Reference Board GNU/Linux
4. Added the following options into /etc/rc.local
/sbin/modprobe binfmt_misc
/bin/mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
echo
':qemu-i386:M::\x7fELF\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x03\x00:\xff\xff\xff\xff\xff\xfe\xfe\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfb\xff\xff\xff:/usr/bin/qemu-i386:'
>/proc/sys/fs/binfmt_misc/register
5. Also copied ld-linux.so.3 (actually ld-2.13.so because ld-
linux.so.3 is a link to that file) from /lib/ to /i386/lib/
6.Now i chroot into /i386 and I get this:
address@hidden i386]# chroot .
[II aI hnve ao address@hidden /]# pacman -Suy
bash: fork: Invalid argument
7.I also downloaded linux-user-test-0.3 from qemu website and ran the test:
address@hidden linux-user-test-0.3]# make
./qemu-linux-user.sh
[qemu-i386]
../qemu-0.14.0/i386-linux-user/qemu-i386 -L ./gnemul/qemu-i386 i386/ls -l
dummyfile
