Hi all, The function of_overlay_fix_path returns NULL in certain error cases but of_overlay_apply_symbols (which is the only caller) does not check the return value. For broken overlays this may result in an exception, which is probably not the best way to deal with this situation. I am not sure though what would be a good way to handle this error condition. Since the call happens in a loop, we may want to ignore the symbol in question and continue? Any thoughts? Best regards, Michael
