Bug#48800 CREATE TABLE t...SELECT fails if t is a temporary

Browse Source 
table

If a temporary table A exists, and a (permanent) table 
with the same name is attempted created with 
"CREATE TABLE ... AS SELECT", the create would fail with 
an error.
   1050: Table 'A' already exists

The error occured in MySQL 5.1 releases, but is not
present in MySQL 5.5.   This patch adds a regression
test to ensure that the problem does not reoccur.
