507	Postgres crash in geos 3.3.0 using postgis st_buffer function	luisico	geos-devel@lists.osgeo.org	"Hi, I have a postgresql server with postgis running on Ubuntu 10.04.
The postgresql version is 9.1.2-1~lucid and this is the postgis_full_version():

POSTGIS=""2.0.0SVN"" GEOS=""3.3.0-CAPI-1.6.1"" PROJ=""Rel. 4.7.1, 23 September 2009"" GDAL=""GDAL 1.8.0, released 2011/01/12"" LIBXML=""2.7.6"" USE_STATS

The postgresql server crashes when I run the next query:

SELECT st_simplifypreservetopology(st_multi(st_buffer(st_buffer(st_buffer(the_geom,-0.09),0.18),-0.08)),0.05) FROM gadm0 WHERE iso='IDN';

Even enabling high postgres debug levels it doesn't give any clue about the problem. It just says the next:
http://pastie.org/3304257

I enabled the core dumps and this is what I got:
http://pastie.org/3304135

Please, let me know if I can provide more information.
Thanks"	defect	closed	minor	3.3.4	Default	3.3.0	Critical	duplicate
