MDEV-15907 ASAN heap-use-after-free This patch fixes an invalid read in fill_effective_table_privileges triggered by a grant_version increase between a PREPARE for a statement creating a view from I_S and EXECUTE. A tmp table was created and free'd while preparing the statement, TABLE_LIST::table_name was set to point to the tmp table TABLE_SHARE::table_name which no longer existed after preparing was done. The grant version increase made fill_effective_table_privileges called during EXECUTE to try fetch the updated grant info and this is where the dangling table name was used. 2019-04-01 11:54:29 +03:00			`PREPARE stmt2 FROM "CREATE VIEW v AS SELECT * FROM INFORMATION_SCHEMA.TABLES";`
