MonetDB server 11.46.0 crashes at BLOBcmp

[fuboat]

Describe the bug
MonetDB server 11.46.0 crashes at BLOBcmp after executing SQL statements through mclient.

To Reproduce

CREATE TABLE a (p_id INT, p_name BLOB);
INSERT INTO a VALUES (1,NULL);
TRACE select * from a where p_name='Lilu';

Expected behavior
Executing statements successfully or throwing errors, instead of breaking down the whole MonetDB server.
