I wonder if it is possible for note_data!=NULL but note_size==0.

If it is possible, then the cleanup ought to be moved earlier.
(FWIW it's ok to have an xfree cleanup with a NULL argument.)

Or if it is not possible, then I suppose the code just above is in
error... not your problem but if you happen to know, I would like to fix
it up.

thanks,
Tom
