[netCDF #ZQX-155900]: segfault with latest netcdf (4.3.1)

Hi Jeff,

I can duplicate the symptoms, so it looks like a bug in ncdump, 
related to the apparent file size (over 140 GB).  nccopy can't be used 
on it either, as it reports:

  NetCDF: One or more variable sizes violate format constraints
  Location: file ../../ncdump/nccopy.c; line 1437

which would be true if it was a netCDF classic format file.

I assume the original data on the DAP server is a netCDF-4 classic
model file.

Thanks for reporting the bug.  Will the file stay at the specified 
URL for a while, until we've determined the cause of the problem?
If not, we'll have to get a copy or synthesize another large file
that demonstrates the problem.
