I guess you will have to create a less complex 'movement' file.

Using the file ns-2.3x/tcl/mobility/scen-3-test, for wireless2.tcl ,
.. then no issues, no 'Segmentation fault' :
The files wireless1-out.nam 32.4MB, wireless1-out.tr 26.8MB are produced.

"less complex" means..? i need scenario of at least 25 nodes,,,then i also need scenarios with increasing number of nodes so as to check protocol performance in MANETs,,,no other option
can u please suggest other alternate solution,,,
i also tried PClinux..facing same issue !!!!!

The OS makes no difference.

I also tested your 'wireless2.tcl' with some old ns executable`s from Ubuntu 10.10 :
The same result : 'Segmentation fault'.

Possible solutions :
The default files <wireless*>.tcl scripts aren't at all robust.
Alternatives ? : ns-2.35/tcl/ex/wpan/wpan_demo*.tcl scripts.
