NetCDF users,
I am developing a program to evaluate most of the new features in
netcdf4 and also the netcdf3 format with our current file format. I
have now implemented packing but I am currently getting a segmentation
fault when packing to a 32bit int (worked for a 16bit int).
Using gdb I can see that it was due to nf_put_var_int (through the f90
interface nf90_put_var). I then used the nf_put_var_int directly for
the packing the 32 bit integers and I found the fault was caused due to
the elemental function int within the call to nf_put_var_int.
e.g.
Call netcdf_check(nf_put_var_int(ncid, i, int(int_packed_data(:,:,:,:))))
replaced with
Call netcdf_check(nf_put_var_int(ncid, i, int_packed_data(:,:,:,:)))
fixes the problem.
I am using this on Linux with the intel compiler (ifort (IFORT) 10.0
20070426 and ifort (IFORT) 9.1 20060927).
Since I have gotten it to work it isnt a major problem but obviously
would like to understand what is going on and whether there is something
I am doing or whether there might be a bug.
Any help appreciated,
Tom
