 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
