Hi,

Could you make available a copy of the netCDF-4 file that has this problem?
That way we could see if we can duplicate the problem with the current version 
of
ncdump, diagnose it, and fix it.

What version of ncdump?  To find out, look at the last line of output from
ncdump -version.

> o   Command "ncdump -x" from the NetCdf4 library on Linux ,written in C

The documentation for the -x option says it only works for netCDF classic files.
It hasn't yet been upgraded to handle the netCDF-4 data model, including any
user-defined types.

The documantation for nco says it hasn't been fully upgraded to handle the 
netCDF-4
data model yet, including user-defined types.
