I tried to reproduce this in current versions (7.2.6, 7.3.7, etc)
and could not. So either it was fixed long ago, or you weren't
sufficiently clear about exactly how to trigger the crash. What
I substituted for the above handwaving was
SELECT * FROM folder;
UPDATE folder SET name = 'z' where name = 'teszt';
SELECT * FROM folder;
DELETE FROM folder WHERE name = 'z';
SELECT * FROM folder;
DELETE FROM folder;
SELECT * FROM folder;
