Superloop 11.0sp1 DHCP Crashes

I am running the superloop simple socket server 3c120 example for 11.0sp1 on a custom board. It works fine with DHCP disabled but with DHCP enabled (*use_dhcp = 1), the entire program crashes at that point. It doesn't time out; it completely dies.  


Looking at Wireshark, nothing is ever being sent. 


Does anyone have any suggestions on how to debug this? 


Here is the output: 

bash-3.1$ nios2-terminal nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster ", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) Superloop Program Starting... calling netmain_init() InterNiche Portable TCP/IP, v3.1 Copyright 1996-2008 by InterNiche Technologies.

I figured out this problem was due to the cticks alarm not being started correctly.
