Hi Roy,
There is a crash found during restart of dhcpcd. Brief bt:
...

   Core was generated by `dhcpcd -4 -f /var/run/dhcp/dhcpcd.conf -c
   /bin/dhcpcd-run-hooks --l'.
   Program terminated with signal SIGSEGV, Segmentation fault.

Detailed bt attached, as well as dhcpcd.conf. I am trying to reproduce 
the crash but not too hopeful if it will occur again.

Let me know if you need any more info.
