[ns] ERROR child killed: segmentation violation

[Amita Singh]

Hi all,
I'm facing a strange problem. If I copy AODV and save it using new name say PROT. Even after changing the supporting files like ns-2.29/tcl/lib/ns-agent.tcl, ns-default.tcl and many others reported in the paper "Implementing a new MANET unicast routing protocol", simulation results in an error:
  ERROR child killed: segmentation violation
I also change the aodv files by replacing aodv with PROT.
What can be the reason behind it?

regards
