[ns] segmentation fault when running snoop

[Bhagyalaxmi Bethala <bethala@csee.umbc.edu>]

hi all,

 I have integrated the snoop patch that is given in the ns webpage.

When i try to run the wireless2.tcl given in marc greis' tutorial with a
change in the following line.

set opt(ll)   LL              ;# link layer type  

to
 
set opt(ll)   LL/LLSnoop      ;# link layer type

It gives me the following warning and segmentation fault.




num_nodes is set 3
