Description:
The following query:

CREATE TABLE t0 (c0 YEAR) AS (VALUES ROW(CAST(DATE '2000-1-1' AS YEAR)),ROW(CAST(1986 AS YEAR)));

Triggers an assertion error at item.cc:6408

assert(max_length == 4);

The compilation parameters are the same as issue 108148:

-DWITH_DEBUG=1 -DWITH_ASAN=ON -DWITH_UBSAN=ON and boost library version 1.77

How to repeat:
Run the query above.
