This was caused by a combination of factors: * MyISAM/Aria temporary tables historically never saved the state to disk (MYI/MAI), because the state never needed to persist * certain ALTER TABLE operations modify the original TABLE structure and if they fail, the original table has to be reopened to revert all changes (m_needs_reopen=1) as a result, when ALTER fails and MyISAM/Aria temp table gets reopened, it reads the stale state from the disk. As a fix, MyISAM/Aria tables now *always* write the state to disk on close, *unless* HA_EXTRA_PREPARE_FOR_DROP was done first. And the server now always does HA_EXTRA_PREPARE_FOR_DROP before dropping a temporary table.
