Ugly build problem with emacs/qemu

Ugly build problem with emacs/qemu

[Sledz, Steffen]

I'm not sure if this is a problem with emacs itself or qemu.

I try to build exactly the same image with the same configuration (fyi CCACHE="") on different computers. On one everything builds fine on the other compiling emacs fails with a segmentation fault. :(

Are the machines you're building on exactly the same? Do they perhaps
have different architectures or distributions? Have you tried updating
the systems?

This looks like a qemu failure to me.

The machines are different.

The one that works fine:
 Ubuntu 8.10
 Linux bfg9000 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux

The one with the problem:
 openSUSE 11.1
 Linux recycler 2.6.27.19-3.2-default #1 SMP 2009-02-25 15:40:44 +0100 i686 athlon i386 GNU/Linux

I agree. But i can't believe, that the different OS my be involved in that. Both are up-to-date. And i thought that all the tools needed to cross-build the packages are build by OE itself.

I don't kow about openSuse, but I remember that Fedora used to have
some kernel patches that did not play well with QEMU. But that was
back on Ferora 7, since then I switched to ubuntu. I don't even
rmember exactly what patch caused the problems, but IIRC it was
security related.

Hmmm, good point it could be SELinux. Could you try disabling that, if
you have it enabled?

It is not SELinux but one kernel patch - linux-2.6-execshield.patch to 
be exact. Rebuild Fedora kernel without that one or use vanilla one.

Took me lot of kernel rebuilds to find that out.

I have selinux but for now it is in enforcing=0 (I have some problem to
resolve before putting it in enforcing mode...but I'll try to disable it
totally)

ah ok I do not have that because I run a stock vanilla kernel.

I've no SELinux running and i've tried the vanilla kernel. But the problem's still there. :(
