Build Identifier:

This is the second report in a series of three issues found while
testing the Air Traffic queries. I'm filing separate reports because
the underlying cause may or may not be the same.

In this case, the attached queries cause the slave mserver5's to crash.

To reproduce, first start three mserver5's as in the attached
restart.sh. Then run demo.sh. This initializes the databases and
runs the failing queries.

Be careful: restart.sh first uses 'killall' to kill ALL existing
processes named 'mserver5'.

I tested this with Mercurial revision 6a7ff140ae05 on the Jul2017
branch.

Reproducible: Always
