The PoC is generated by my DBMS fuzzer.

CREATE TABLE t1 (
  x VARCHAR,
  k VARCHAR
);
CREATE VIEW t1 AS SELECT x, k FROM t1;
INSERT INTO t1 VALUES ('x', 'y');

ways to reproduce (write poc to the file '/tmp/test.sql' first):

# remove the old one
docker container rm virtdb_test -f
# start virtuoso through docker
docker run --name virtdb_test -itd --env DBA_PASSWORD=dba openlink/virtuoso-opensource-7:7.2.9
# wait the server starting
sleep 10
# check whether the simple query works
echo "SELECT 1;" | docker exec -i virtdb_test isql 1111 dba
# run the poc
docker exec -i virtdb_test isql 1111 dba < "/tmp/test.sql"
