I would start debugging at line 97 of the file "f90/netcdf_test.f90":

    call check(nf90_put_var(ncFileID, pressVarID, pressure(:, :, 2), start = (/ 
1,
   1, 2 /)) )

This is where the incorrect values are written to the output netCDF
file.  From within the nf90_put_var routine, I would look at the first
pressure value; it should be 962 (but is probably 950).

I think it's a problem with the pgf90 compiler.  I think the compiler
isn't correctly handling the "pressure(:, :, 2)" expression.
