[ferret_users] Possible bug in Ferret 6.7 vs 6.64

[Gary Strand <strandwg@xxxxxxxx>]

I'm getting an error from Ferret 6.7 that doesn't occur when using Ferret 6.64. This is a straightforward netCDF file that happens to have a field defined on a curvilinear grid that meets CMIP5 requirements.

Under Ferret 6.64:

        NOAA/PMEL TMAP
