Running this query against Postgis 1.5 causes a core dump:
SELECT ST_intersects(
geomfromtext('POLYGON((31.904296875 67.32421875,14.58984375

Running against Postgis 2.0 gives the following error (much preferred to
get an error than a core dump!):
ERROR: GEOSIntersects: TopologyException: side location conflict at
31.81640625 67.32421875
CONTEXT: SQL function "st_intersects" statement 1
Both are using geos version: '3.3.5-CAPI-1.7.5'.
Unfortunately upgrading to Postgis 2 is not an option for us.
Our platform is Solaris 10 x86 using 64 bit builds.
