[ns] AODV segmentation fault in Priqueue.cc filter()

[Valerie Alandzi]

   Hi,

When I run AODV simulations, I get a segmentation
fault everytime  Priqueue::filter() gets called in
aodv rt_ll_failed(). Here is what I get from gdb:

Program received signal SIGSEGV, Segmentation fault.
0x08125b32 in PriQueue::filter(int) (this=0x0, id=8)
at queue/priqueue.cc:158
158             for(p = q_->head(); p; p = p->next_) {
(gdb) bt

Is this a bug in Ns2 or in my code ??? Is there a
solution to this ???? Your help is appreciated !!!
