Bug #23279858: MYSQLD GOT SIGNAL 11 ON SIMPLE SELECT

Browse Source 
NAME_CONST QUERY

ISSUE:
------
Using NAME_CONST with a non-constant negated expression as
value can result in incorrect behavior.

SOLUTION:
---------
The problem can be avoided by checking whether the argument
is a constant value.

The fix is a backport of Bug#12735545.
