Hi Sergei,
It fixes the reported crash, and additionally inconsistencies when comparing temporal columns to empty strings:
In some cases it returned rows, in other cases it returned no rows, depending on: - the engine - the type of comparison arguments (columns vs literals). - presence of an index
Now everything works in the same way.
Note, this additional problem is not 10.1 specific, it existed in 10.0. But 10.0 and 10.1 worked differently in certain cases.
Ok to push. In 10.0, right? And, by the way, please send a full commit next time, not just a diff. It was quite a challenge to figure out what was the bug and what were you fixing without a commit comment :( Regards, Sergei Chief Architect MariaDB and security@mariadb.org
