Bug #20439913 CREATE TABLE DB.TABLE LIKE TMPTABLE IS BINLOGGED INCORRECTLY - BREAKS A SLAVE

Browse Source 
Analysis:
In row based replication, Master does not send temp table information
to Slave. If there are any DDLs that involves in regular table that needs
to be sent to Slave and a temp tables (which will not be available at Slave),
the Master rewrites the query replacing temp table with it's defintion.
Eg: create table regular_table like temptable.
In rewrite logic, server is ignoring the database of regular table
which can cause problems mentioned in this bug.

Fix: dont ignore database information (if available) while
rewriting the query
