Please try the following script:
mkdir /tmp/50m
sudo mount -t tmpfs -o size=50M tmpfs /tmp/50m
export PGDATA=/tmp/50m/tmpdb
initdb
pg_ctl -l server.log start
cat << 'EOF' | psql
CREATE TEMP TABLE t (a name, b name, c name, d name);
INSERT INTO t SELECT 'a', 'b', 'c', 'd' FROM generate_series(1, 1000) g;
COPY t TO '/tmp/t.data';
SELECT 'COPY t FROM ''/tmp/t.data''' FROM generate_series(1, 100)
\gexec
EOF
which produces an unexpected error, a warning, and an assertion failure,
starting from b8bff07da:
