This isn't really clear from the example, but you need to put the 
bottom part in a function (e.g. main), including the variable 
initializations. I.e.:

----
void main()
{
     // create instances of each type
     Fiber derived = new DerivedFiber();
     Fiber composed = new Fiber( &fiberFunc );

     // call both fibers once
     derived.call();
     composed.call();
     printf( "Execution returned to calling context.\n" );
     composed.call();

     // since each fiber has run to completion, each should have 
state TERM
     assert( derived.state == Fiber.State.TERM );
     assert( composed.state == Fiber.State.TERM );
}
