Based on the core bt it looks like some run time exception has resulted into the the program termination as the exception was not caught since throw was invoked without argument.Hence the program got terminated and core dumped.But we donot know the root cause that resulted into this exception.Please let me know how to debug this core file as it is not loading the symbols for this particular thread.
