Galina Shalygina 55163ba1bd MDEV-16803: Pushdown Item_func_in item that uses vectors in several SELECTs ...

The bug appears because of the Item_func_in::build_clone() method.
The 'array' field for the Item_func_in item that can be pushed into
the materialized view/derived table was built in the wrong way.
It becomes lame after the pushdown of the condition into the first
SELECT that defines that view/derived table. The server crashes in
the pushdown into the next SELECT while trying to use already lame
'array' field.

To fix it Item_func_in::build_clone() was changed.
