Warning about dhcpcd-10.5.0 with arm

[Adolf Belka]

Hi All,

Some information. I have a RPi with Arch Linux installed on it which I 
use as my dhcp server on my orange network.

The Arch Linux ARM group are separate from Arch Linux. They had not done 
an update to 10.4.x so I was still on 10.3.2.

I ran an update and they updated dhcpcd to 10.5.0

After the update dhcpcd failed to start and the logs showed it was 
having a core dump when trying to start.

I downgraded to 10.2.3 and everything worked fine, Upgraded to 10.5.0 
again and it had the core dump again and downgrading again made it work.

So on my arm based rpi with arch linux I am staying with 10.3.2 for the 
moment.

It would probably be worth testing the 10.5.0 version on an arm IPFire 
to see if it is a general issue or only for some hardware/os combinations.

Regards,

Adolf.

I compiled and pushed dhcpcd 10.5.0 a few days ago and got it running
since then on Core 203 (x86_64). No seen problems so far - its running
now for 5 days 17 hours 6 minutes (watched by 'monit').
