 The following sequence causes a crash in BOX3D_combine(), line 348, on
 "GSERIALIZED *geom = (GSERIALIZED*)PG_DETOAST_DATUM(PG_GETARG_POINTER(1))"

 {{{
 CREATE TABLE test_crash_st_extent ( foo VARCHAR )
 SELECT
 AddGeometryColumn('public','test_crash_st_extent','wkb_geometry',0,'GEOMETRY',2)
 INSERT INTO test_crash_st_extent (foo) VALUES ('bar')
 SELECT ST_Extent(\"wkb_geometry\") FROM test_crash_st_extent
 }}}

 Attached patch fixes the segfault
