Script where sim fails

Hi,

I am trying to run the following case:

TOPOLOGY:

     WIRED CSMA             WIRELESS CHANNEL
   ______________
   O            O  ))              (( O ))   RANDOMLY PLACED IN 500x500 map
   Nk           N0                N1 ..... N(k-1)


where nNodes = k-1

The following happens:

./waf --run "scratch/wifi-mesh -nNodes=10"  #Works
./waf --run "scratch/wifi-mesh -nNodes=39"  #Works
./waf --run "scratch/wifi-mesh -nNodes=40"  #Fails
./waf --run "scratch/wifi-mesh -nNodes=41"  #Works
./waf --run "scratch/wifi-mesh -nNodes=50"  #Fails
./waf --run "scratch/wifi-mesh -nNodes=100" #Fails

when it fails, I get:

assert failed. file=../src/internet-stack/ipv4-l3-protocol.cc, line=671,
cond="packetCopy->GetSize () <= outInterface->GetMtu ()"
Command ['/home/cortes/ns3/ns-3-dev/build/debug/scratch/wifi-mesh',
'-nNodes=40'] exited with code -11 

Thanks,
