[postgis-devel] Issue 119 in postgis: ST_AsSVG crashedDBbackendwith large geometries.

[Obe, Regina]

Olivier,

I retested on my same box (blowing out my whole svn and redownloading from scratch and still run into the same issues.).  I'll be able to test on windows aond my other OpenSUSe tomorrow.

Anyrate I am running
"POSTGIS="1.4.0SVN" GEOS="3.1.0-CAPI-1.5.0" PROJ="Rel. 4.6.0, 21 Dec 2007" USE_STATS"  (also verifeid it was built minutes ago)

"PostgreSQL 8.3.1 on i686-pc-linux-gnu, compiled by GCC gcc (SUSE Linux) 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036]"

I wonder if its my gcc or something that is the culprit.  Below is list of things that works and what crashes. Seems to crash when it gets to polygons. If others could test on their platforms that would be super.

--Point works.
 SELECT ST_AsSVG(foo1.the_geom)

                        FROM ((SELECT ST_SetSRID(ST_Point(i,j),4326) As the_geom
                FROM generate_series(-10,50,15) As i
                        CROSS JOIN generate_series(40,70, 15) j)) As foo1;

--lines work
        SELECT ST_AsSVG(foo1.the_geom)

                        FROM ((SELECT ST_MakeLine(ST_SetSRID(ST_Point(i,j),4326),ST_SetSRID(ST_Point(j,i),4326))  As the_geom
                FROM generate_series(-10,50,10) As i
                        CROSS JOIN generate_series(40,70, 15) As j
                        WHERE NOT(i = j))) As foo1;


--polygon crashes server
        SELECT ST_AsSVG(foo1.the_geom)

                        FROM ((SELECT ST_Buffer(ST_SetSRID(ST_Point(i,j),4326), j)  As the_geom
                FROM generate_series(-10,50,10) As i
                        CROSS JOIN generate_series(40,70, 20) As j)) As foo1;

Ok, let will see...
on my own:

  POSTGIS="1.4.0SVN" GEOS="3.0.2-CAPI-1.4.2" PROJ="Rel. 4.6.1, 21  
August 2008" USE_STATS
  Linux Slackware 12.1
  postgis r 3819
  => Ok on the whole garden test


POSTGIS="1.4.0SVN" GEOS="3.1.0-CAPI-1.5.0" PROJ="Rel. 4.6.0, 21 Dec  
2007" USE_STATS
Mac Os.X 10.5
postgis r 3817
  => Ok on the whole garden test
