That's true. I had the same core dump when using sample scenario and
connection pattern files (under tcl/mobility/scene/ directory) with
long trials, like 900 sec. 

So, I decreased running time into 10 sec and created new sc & cp files. 
(The new files are for only two nodes and one connection between
themselves.) Now, core dump does not happen. 
But, still something wrong...
