Reproducible: Always

Steps to Reproduce:

  1. Start mserver5 (MonetDB 5 server v11.21.4)
  2. download and save attached select4a.test.sql file
  3. Mtest.py select4a.test

Actual Results:

bash-4.2$ Mtest.py select4a.test

Running in sql/test
15:56:44> select4a.test 0.621s ABORTED

!ERROR: Testing FAILED SIGNIFICANTLY (1 out of 1 tests failed)

 1 out of   1 tests caused an abort (assertion failure)
     sql/test/SQLite_sqllogictest/select4a.test

Output of select4a.test.err:

6 lines, 31 words, 297 chars in lines not matching '^$|^|^= = 6 lines, 31 words, 297 chars in lines not matching '^$|^

ACTION= mapi_query_done
QUERY = -- 9 values hashing to 0242ff524f6efe4a8115ad23f4d8659a
ERROR = !write error on stream

Expected Results:

No assertion failure.
The problem is somewhere in the INTERSECT part of the query as without it, it does not fail.
