on a
raring host with qemu-user-static version 1.4.0+dfsg-1expubuntu2
a libreoffice build has now been going for 6 days with no failures
yet. (How long does that thing go on? :)
Unless you say otherwise I'm now going to shift to looking into the

javac switched from hanging forever to segfaulting.

so you'd recommend testing for the javac hang with

Well, you can try, but I don't think it is very likely to help. The
patch is a hacky workaround for select() in particular, not for the
entire class of hangs.

I see the same thing javac hanging. This is with a raring chroot on

and my linux-user patches

John: it would be interesting to try to determine whether that hang has
the same root cause as the cmake and boehm-gc hangs, ie the thing that
is supposed to post the futex is a signal handler whose signal comes in
either just before or during the syscall [either way, the emulated code

@John,
as the bug description was about the 12.04 libreoffice build, i'm
actually using a raring host with 1.4.0 qemu-user-static, with a
*precise* armhf container. The precise libreoffice has been building
all day friday and friday so far with no incidents.

Trying to build on a raring amd64 host in a raring armhf chroot, two

John: you might also like to try with this patchset applied:

segfaults and other problems (as the cover letter describes) but it's possible

It turns out it is javac in raring chroots which gives me the problem.
I finally realized that the bug is about a libreoffice build in a
precise chroot. I'm running a build (which has been running most of the
day) with qemu-arm-static from a hand-built qemu source tree with this
morning's latest
Thanks, I'll give that a shot!

Thanks for the patch. John, since you're going to be doing more QEMU work in
future I'd encourage you to go through the process of submitting it to
upstream's mailing list and shepherding it through the patch review process.
Upstream's patch submission guidelines are here:
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Peter, sorry I attached this quick patch to the bug for Serge to try
out with the intent of sending a proper patch upstream later.
-BEGIN PGP SIGNATURE-
Version: GnuPG v1.4.11 (GNU/Linux)
Comment: Using GnuPG with undefined -
The patch at least allows java to run without segfaulting. I have not
tried to build libreoffice yet.
Late in 2012 libc started using FUTEX_WAIT_BITSET instead of FUTEX_WAIT
so teach qemu about it so it will forward the call to the host kernel
rather than returning -TARGET_ENOSYS. The patch

Serge, I asked Alex to escalate this because it has required us to make
a devirtualised PPA for a commercial project that involves libreoffice

it's going to be using Ubuntu build resources rather than the usual PPA

Well, the first step would be to provide a reasonably tractable set of
reproduce instructions (at minimum, something like do this to set up a
chroot, then in the chroot run this command and watch it SIGILL.) Also
checking it still repros on 1.4.0 (just released) would be nice (though

On a stock ubuntu raring system, I did
sudo apt-get install lxc qemu-user qemu-user-static
sudo lxc-create -t ubuntu -n r1 -- -a armhf
sudo lxc-start -n r1
# log into console as ubuntu/ubuntu, there do:
sudo apt-get install ca-certificates-java
That gave me the attached error (reproducible).
