Software versions

• MonetDB version number: v11.49.1 (Dec2023)
• OS and version: Ubuntu 20.04
• From docker image monetdb/monetdb:Dec2023 (or monetdb/dev-builds:default)

An example of steps to reproduce in docker container (write the poc into /tmp/test.sql first):

docker container rm monetdb_test -f
docker run -e MDB_DB_ADMIN_PASS=monetdb --name monetdb_test -itd monetdb/monetdb:Dec2023
docker exec monetdb_test bash -c 'echo -n -e "user=monetdb\npassword=monetdb\n" > /root/.monetdb'

sleep 10
cat /tmp/test.sql | timeout 5s docker exec -i monetdb_test mclient monetdb     # run test case

if docker exec monetdb_test bash -c "grep '[m]server5' /proc/*/cmdline -lR"; then
    echo "[INFO] Server normal."
else
    echo "[CRASH] Mserver5 process does NOT exist."
fi

It can also be reproduced on the docker image monetdb/dev-builds:default.
