When dhcpd is configured to serve addresses from a huge pool of
addresses it crashes. Sample config:

subnet 10.0.0.0 netmask 255.0.0.0 {
   range 10.0.0.2 10.255.255.254;
}

Tried with dhcp-4.1.1-P1 and dhcp-4.3.2rc1.

When I decrease size of the address pool to for example
range 10.0.0.2 10.100.255.254;
dhcpd runs OK (or claims that it has
'No memory for address range 10.0.0.2-10.100.255.254').

It's of course not a real use-case, but it might reveal a bug somewhere.
I don't have any patch, just a backtrace and valgrind output, see 
attachments.
They are from dhcp-4.3.2rc1, no patches applied.
