Build Identifier:

Mserver receives a SIGSEV in an aggregation query with IN clause. Tested in the latest development version of the Jul2017 branch.

Reproducible: Always

Steps to Reproduce:

  1. CREATE TABLE tab2(col0 INTEGER, col1 INTEGER, col2 INTEGER);
  2. SELECT 9 - - col1 FROM tab2 GROUP BY col1 HAVING - CAST ( NULL AS INTEGER ) IN ( + - SUM ( - + 47 ), + MIN ( col2 ) );

Actual Results:

Mserver receives a SIGSEGV in a rel_logical_exp call.

Expected Results:

An empty result set.

GDB output:

Thread 6 "mserver5" received signal SIGSEGV, Segmentation fault.

2628 le = exp_column(sql->sa, exp_relname(le), exp_name(le), exp_subtype(le), le->card, has_nil(le), is_intern(le));
