Hello.

received wrong for a receiver, what happen? Do it send a message to
sender? Thank you.

No. To quote RFC 792:

http://tools.ietf.org/html/rfc792

The ICMP messages typically report errors in the processing of
datagrams. To avoid the infinite regress of messages about messages
etc., no ICMP messages are sent about ICMP messages. Also ICMP
messages are only sent about errors in handling fragment zero of
fragemented datagrams. (Fragment zero has the fragment offeset equal
zero).
