 This is a long standing bug, but not sure how easy it is to go back and
 fix for 1.5.  I didn't notice this since I had excluded curved geometries
 from my garden tests and hadn't put them back.  I don't think its an issue
 with all curved polygons though

 -- This crashes --

 {{{
 SELECT ST_AsEWKT(ST_LineToCurve(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
                                         ORDER BY i, j, i*j;
 }}}

 -- this works fine
 {{{
 SELECT ST_LineToCurve(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
                                         ORDER BY i, j, i*j;
 }}}


 -- this one  works fine too -

 {{{
 SELECT ST_AsEWKT(ST_GeomFromEWKT('SRID=4326;CURVEPOLYGON(CIRCULARSTRING(0
 0, 4 0, 4 4, 0 4, 0 0),(1 1, 3 3, 3 1, 1 1))'));
 }}}
