Hmmm, gdb won't produce useable results on my x86_64 machines - I don't
actually have any i386 systems left!
Can you provide a backtrace from each of the cores? At least one is from
6.11.0 i think.
$ gdb ./dhcpcd-6.11.0
(gdb) core dhcpcd-1464212601-11.27823
(gdb) bt
That should give the needed information.
