[ns] assert doesn't work in ns?

[Li Li <lili@cs.cornell.edu>]

 c++ "assert" statement doesn't work in my ns-2.1b6 c++ code. I have tested
it with simple c++ programs using the same c++ compiler. It works fine. So
it's not a compiler problem. Can anyone tell me how to make assert work in
ns c++ code?

Thanks,

Li
