This seems to be due to the recursion in

>        struct ObservationDataStruct {
>                QualifiedCodeStr code;
>                sequence<ObservationDataStruct> composite;

something as simple as this fails as well

====
struct teststruct {
  sequence<teststruct> composite;
  };

interface test {
 void testie( in teststruct test1 );
};
====

What I think seems to be happening is that the recursion causes
marshal_populate() in orbit-idl-genmarshal.c to run out of memory
and fail when trying to create a new marshalling node?

I'm surprised this type of recursion is legal ;)
