[netCDF #UPO-861727]: getVar crashed with compressed file

Let me make sure I understand.
1. You have some uncompressed file, call it u.nc.
2. You compress it using nccopy -d 1 u.nc c.nc
   to produce the file c.nc
3. You then try to read the c.nc file using a program that calls
   getVar and when you do so, your program crashes.
Do I have that right?
