Build Identifier:

The server receives a SIGABRT signal on an aggregation query with a NOT IN condition in the HAVING clause. Tested on the latest development version of the Jul2017 branch.

Reproducible: Always

Steps to Reproduce:

1. CREATE TABLE tab1(col0 INTEGER, col1 INTEGER, col2 INTEGER);
2. SELECT cor0.col1 FROM tab1 AS cor0 GROUP BY cor0.col1 HAVING NULL NOT IN ( - cor0.col1 );

Actual Results:

The server receives a SIGABRT signal from an assert(0) call in exp_bin.

Expected Results:

An empty result set.
