  Thanks to some help from David Fousler from SGI, I figured out
the bug in the Buggy program.  I had been calling cxOutputDataSet
routine in my routine around my lattice, a then shipping it
down the wire with the cxOutputDataFlush routine.  This worked,
but then the module data wrapper routine followed my good data
with a NULL lattice. This left the output port with NULL hanging
off it when it wasn't connected, causing the funky behavior I was
seeing.

  The moral of the story is to not mix calls to cxOutputDataSet
and cxOutputDataSet in routines that use the module data wrapper.
Oh well...
