Subject: dbus start script segmentation fault

Date: Mon, 11 May 2009 10:44:04 +0800

Package: dbus
Version: 1.2.14-2
Severity: grave

Dbus 1.2.14-2 failes to install due to start script segmentation fault,
which makes it half-installed and unusable, hence severity grave.

It is strange that all the envvars are empty.  Downgrading to version
1.2.12-1 does not have the problem.  Please contact me if further

I can confirm this problem on mips(el). It seems to be a toolchain issue on this
architectures:
1.) The 1.2.12-1 package from the archive works fine. If I recompile it with a
current toolchain on sid, I the get same behaviour.
2.) Compiling 1.2.14-2 with the lenny toolchain produces working binaries.

I had a quick discussion with aurel on irc, which confirms that:

As aurel said, he doesn't have time to look into this immediately.

That's why I CCed the debian-release team. There are some important rdeps of
dbus, like libgnomevfs2 and gconf2-common. Apparently this leads to build
failures for GNOME packages [1], where dbus is installed as a dependency of
those libs. (I'm still puzzled though, why dbus is started at all. I thought the
buildds had a policy-rc.d which prevents that).

As this will block the successful compilation of GNOME packages on mips(el) I'm
asking the release team if I should upload 1.2.14-2+b1 packages for mips(el)
which have been built with a lenny toolchain, until aurel had time to properly
investigate that (and provide a proper fix).

Cheers,
Michael

Yes, I think that's a bug of the buildd, dbus should not be started in
the chroot.

Ok, CCing the mips buildd maintainers.
Hopefully they can get the mips buildds fixed quickly so ongoing transitions are
not blocked by this.

The problem appears as dbus is creating dbus-daemon as a broken pie
binary. Disabling -pie workaround the problem. I don't know yet what has
introduced this regression though.

I CCed Matthias. Maybe he has an idea as gcc/binutils wiz.

I'm cloning the bug for gcc, because this is (one of) the packages of the build
toolchain that was updated between the 1.2.12-1 and 1.2.14-2 build of dbus. The
last upload of binutils was before dbus 1.2.12-1, and this binary was still working.



The following note in the build log [1] might be related:


dh_shlibdeps -pdbus
BFD: debian/dbus/usr/bin/dbus-daemon(.rel.dyn): relocation 164 has invalid
symbol index 0
BFD: debian/dbus/usr/bin/dbus-daemon(.rel.dyn): relocation 165 has invalid
symbol index 0
dh_installdeb -pdbus-x11

Cheers,
Michael
