The unsound function dump_code_load_record uses from_raw_parts to directly convert the pointer addr and len into a slice without any validation and that memory block would be dumped.

Thus, the 'safe' function dump_code_load_record is actually 'unsafe' since it requires the caller to guarantee that the addr is valid and len must not overflow. Otherwise, the function could dump the memory into file illegally, causing memory leak.
