#2216 closed defect (fixed)

ST_GeomFromGeoJson MultiPolygon crash

Reported by: halset Owned by: strk
Priority: blocker Milestone: PostGIS 2.0.3
Component: postgis Version: 2.0.x
Keywords: history Cc: mateusz@…


I am having trouble parsing a MultiPolygon GeoJSON.

Some googling lead me to, so I upgraded from 2.0.1 to 2.0.2. At least, I think I did. I installed postgis and did a "ALTER EXTENSION postgis UPDATE TO '2.0.2';" in my database. The query in #2130 does work in my database.

The sql that crashes in my database are attached.

postgis_full_version() returns POSTGIS="2.0.2 r10789" GEOS="3.3.5-CAPI-1.7.5" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.9.2, released 2012/10/08" LIBXML="2.7.8" LIBJSON="UNKNOWN" RASTER

This is with json-c 0.9. I have tried with json-c 0.10 as well, but it still says LIBJSON="UNKNOWN" and crashes.

This is on a mac, but I have the same problem on ubuntu linux

r11119 moves the code to liblwgeom (and fixes a leak). Will look at your patch right now.

r11120 adds the new testcase in liblwgeom cunit and applies your patch (thanks!) in trunk, r11121 adds the test to regress/ r11122 puts all to 2.0 branch.
