If we start mserver and then we create the following function:
CREATE FUNCTION funcTest(nme varchar(40))
RETURNS STRING
BEGIN
RETURN ( SELECT name
FROM _tables
WHERE name = UPPER(nme)
);
END;
Stop mserver and start it in readonly mode and run the following query:
SELECT s.id
from _tables s, _tables l
where
s.name = funcTest('QSO');
At the mclient side I get the following:
[goncalve@alviss queries]$ mclient current debug sql < test
MAPI = monetdb@localhost:55000
QUERY = SELECT s.id
from _tables s, _tables l
where
s.name = funcTest('QSO');

NOTE: The mserver complains about "schema statements cannot be executed on a readonly database." But there is not any DDL query, except the temp table that is created inside the function.
When the mserver is not on readonly mode everything works fine.
Reproducible: Always
Steps to Reproduce:
Described in "details".
Actual Results:
crash in the mserver
Expected Results:
SELECT s.id
from _tables s, _tables l
where
s.name = funcTest('QSO');
% sys.s table_name
% id name
% int type
