Hi Rose,

Sorry to take so long to respond to your question.

We can't duplicate the problem here, and have not seen a report of that
assertion violation before.  All I can suggest is that you update to a 
more recent version of netCDF, for example version 4.1.1, and see if the
problem goes away.  If it doesn't and you can supply us with a dataset
and relatively small program with which we could reproduce the error, we
might be able to supply a fix.

By the way, you can build a netCDF-3 library from a netCDF 4.x source by
just using the configure option --disable-netcdf-4 when you run the
configure script.
