Alex,

Replication runs as system user, so it doesn't need special privilege to create a table. I think the temporary table is only belonged to the account who created, so I'm not surprised if it cannot be replicated to a different server.

I did test on 5.1. It didn't replicated, but there was no error message, and the replication is still running without interruption. 

Why do you have to create temporary table?
