Need help understanding gdb message output

[Boong Baang]

I use a custom trace file generated in SUMO and use it in vanet-routing-compare.cc. I change all variables in the program so that the mobility is taken from the trace file. I ensure number of users is same in the trace file and the one specified through command line. First, I get the error: 

Command ['/home/ns3/ns-3.29-modified/ns-3.29/build/scratch/vanet-routing-compare', '--totaltime=400', '--protocol=0', '--scenario=2'] terminated with signal SIGIOT. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

Running on gdb -> ./waf --run scratch/vanet-routing-compare --command-template="gdb --args %s --protocol=0 --scenario=2 --nodes=50",

which leads to the error below:

[Thread debugging using libthread_db enabled]
