Description:
I think this is related to Bug #110577. Run:

CREATE TABLE t0 (c0 VARCHAR(32) AS (_binary 'a' COLLATE `binary`));
--ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'binary))' at line 1

This: SELECT _binary 'a' COLLATE `binary`; runs fine.

I think the issue arises from `binary` being a keyword. The create table succeeds if I try with another charset and collation combination.

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 statements above.

This morning I found another corner case:

mysql> CREATE TABLE t0 (c0 CHAR(1) AS (X''));
ERROR 1054 (42S22): Unknown column '0x' in 'generated column function'

Sorry for the last comment, it doesn't apply to version 8.3.0, but the initial case still applies.
