The function 'erl_xreceive_msg' returned garbage in the 'to' and 'to_name' members of the message. The reason for that was found in the 'erl_do_receive_msg' function. When no 'pid' is provided by the sender, like when doing rpc calls as those uses registered name sends, it doesn't initialize the 'to' member and also the 'to_name' member is copied by the function.
