dhcpcd v6.7.1 'realloc() error"

Hi Roy,

I've recently turned on a couple DHCPv4 scope options in the Win2012 DHCP Server that our 'dhcpcd' clients talk to. Unfortunately this has resulted in the following dhcpcd error (and termination):

*** Error in `dhcpcd': realloc(): invalid next size: 0x0942d820 ***

When I remove these options and reboot (restart dhcpcd) the error goes away and 'dhcpcd' is back to normal. As a result I need to either turn off DHCP completely on our 'dhcpcd' targets or remove the problematic DHCPv4 server scope options.

The two scope options are:
066 Boot Server Hostname (value is an IP address)
067 Bootfile Name (value is "pxelinux.0")

Any ideas?

Thanks,
-David

PS: Other DHCP clients seem fine with these scope options (i.e., Windows DHCP client, the Linux kernel when configured for autoip via DHCP, etc.).
