That is bizarre!

The only idea I've been able to come up with is to see if I can
duplicate the problem using the HDF C libraries, rather than working
through IDL. If so, then it's an HDF issue, and I'll check with the HDF
help desk. If not, it's an issue with the IDL wrappers for the HDF
functions, and I'll have to talk to IITVS.
