[netcdfgroup] segmentation fault when nc_close

Hi,

I'm using the netcdf C interface and CDI  to read and write very  large netcdf 
files.
My script is not very complicated, the netcdf interface gives me greater access 
to the data in the netcdf file than CDI but cdi gives me better access to the 
time steps in the file.
After accessing the data, I calculate the monthly averages and then write them 
to a new netcdf file for each month.
Over 1 year this is done 8 times each month. The program works for the most 
part well but when the final month's data is written and I close the newly 
created netcdf file, I get a segmentation fault.
The file seems to be closed and the data looks good but I cannot trace the 
problem. I placed a simple print statement after the nc_close command and error 
handling function but this statement is never reached.

I would like to know if there is anyone who have encountered something similar 
and can give some tips as to where to look and what may be the problem. I used 
the example given in the example map in the netcdf installation.
I can send the script if anyone is so kind as to assist me with this debugging 
:-)


Sincerely,
Marston
