Build Identifier:

The server gets an assertion error in an complex aggregation query with a NOT IN clause.

Reproducible: Always

Steps to Reproduce:

1. CREATE TABLE tab2(col0 INTEGER, col1 INTEGER, col2 INTEGER);
2. SELECT ALL - 89 FROM tab2 GROUP BY col1, col1 HAVING - CAST ( NULL AS INTEGER ) * + - 17 + + - COUNT ( * ) NOT IN ( + MAX ( 44 ) );

Actual Results:

Mserver5 gets an assertion error.

Expected Results:

An empty result set.

The assertion error:

mserver5: rel_bin.c:564: exp_bin: Assertion `s' failed.
