Please enter a FULL description of your problem:
- ------------------------------------------------

The LSEGs are worse in today's distribution than they were last week.
Simply trying to select rows with LSEGs dumps core on me.

I can't really send you more information. I was trying to track down a bug
in dist_ps, but my sense from last week's snapshot is that the problems
with dist_ps were *not* related to the slope of the segment.

Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:
- ----------------------------------------------------------------------

foo=> \i segtest.sql
create table a (name text,p point);
CREATE
create table b (name text,s lseg);
CREATE
insert into a values ('point1', '(5,5)'::point );
INSERT 147742
insert into b values ('seg1', '[(1,1),(9,5)]' );
INSERT 147743
select * from b;
FATAL:  unexpected results from the backend, it probably dumped core.FATAL:  une
xpected results from the backend, it probably dumped core.EOF
foo=>
