Bug reported by Philip Huynh: phuynh@uccs.edu

when we ran the simulation script wimax-ipv4.cc on the OS CentOS 5 or Fedora 11, the script ran through ok with the parameter nbSS < 20. But if the nbSS > 20, i.e --nbSS=30, the script has been stoped with the error as following:

[root@nctuns6 ns-3.9]# ./waf --run "scratch/wimax-ipv4-1 --nbSS=50"
Waf: Entering directory `/root/ns-allinone-3.9/ns-3.9/build'
Waf: Leaving directory `/root/ns-allinone-3.9/ns-3.9/build'
'build' finished successfully (1.266s)
Command ['/root/ns-allinone-3.9/ns-3.9/build/debug/scratch/wimax-ipv4-1', '--nbSS=50'] terminated with signal SIGSEGV. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").
