Bug#12770 DESC cannot display the info. about temporary table 

Bug#14387 SHOW COLUMNS doesn't work on temporary tables.
Bug#15224 SHOW INDEX from temporary table doesn't work.
  Restore thd->temporary_tables to be able to process
  temporary tables(only for 'show index' & 'show columns').
  This should be changed when processing of temporary tables for
  I_S tables will be done.
