[avahi] arm memory alignment problems

[pHilipp Zabel]

Hi!

I have a problem getting avahi-daemon to run on an ARM machine:

root at ipaq-pxa270:/etc/udev/rules.d# echo  5 > /proc/cpu/alignment #
(SIGBUS on alignment errors)
root at ipaq-pxa270:/etc/udev/rules.d# gdb avahi-daemon
(gdb) run
Starting program: /usr/sbin/avahi-daemon
Daemon 4388 killed: No such process; removing PID file.
(/var/run/avahi-daemon//pid)
Found user 'avahi' (UID 44) and group 'avahi' (GID 64003).
Successfully dropped root privileges.
avahi-daemon 0.5 starting up.
Loading service file /etc/avahi/services/ssh.service.
New relevant interface usb0.2.
Network interface enumeration completed.
Registering new address 192.168.47.2 on usb0.

Program received signal SIGBUS, Bus error.

ARM only supports 32 bit aligned memory accesses, afaik.
Does anybody have an idea how to fix this?
