Hi All,
I ran NS-2 simulation using one TCP source and one TCP sink i.e.
just two nodes. I started simulation at 10 and end time is 50. I got the
following error almost at the end of simulation i.e. at time 49.986260487
Program received signal SIGSEGV, Segmentation fault.

when I googled this problem I found similar post at
http://old.nabble.com/segmentation-fault-while-running-ns2.29-on-cygwin-and-instvar-global-scope-error-when-running-on-RHL-9-td29486777.html
but no body posted a solution.
Thanks
