Problem with pfMergeBuffer

I have been attempting to create a separate DBASE function that creates
some geometry and adds it to the scene. However I have found that the
order in which I create the nodes is critical. For example if I create a
pfGroup and then create a pfGeode and attach the geode to the group the
pfMergeBuffer in my separate DBASE function works. If however I create
the pfGeode and then create the pfGroup the pfMergeBuffer crashes at the
following location.

An initial work around is to create them in the same top down order that
they will appear in the scene graph, but this is difficult for some of
the code I want to execute in the DBASE function.
