$ cat -n netcdf/netcdf_expanded.f90:
...
  1470  print *,shape(values)
  1471  print *,size(values)
  1472  print *,is_contiguous(values)
  1473  
  1474         nf90_put_var_1D_EightByteReal = &
  1475            nf_put_vara_double(ncid, varid, localStart, localCount,
values)
  1476       end if
  1477     end function nf90_put_var_1D_EightByteReal
...

gets me:

           1
           1
 T

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
