For example, If I return the "CORBA::string_dup(0)" as the NULL value for
char* return type. I'm getting the following error message

omniORB: Application check failed. This indicates a bug in the application
 using omniORB.  See the comment in the source code for more info.

Vivek - I tried Object::_nil() also. Still problem is alive.

You should never return NUL for any value/data type.
You should return Object::_nil() .
In other cases like lists, you should return blank list instead of NULL.
