 Running st_3dintersection on the above configuration fails and causes a
 core dump in the database.  See attached for sample data creation and
 query scripts.


 (This same query works fine on the following configuration:
 POSTGRES: "PostgreSQL 10.19 (Ubuntu 10.19-0ubuntu0.18.04.1) on x86_64-pc-
 linux-gnu, compiled by gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0, 64-bit"
