 I know this is a crazy test.  This error is happening on my garden test on
 my 32-bit windows 7 box with r8242.

 I haven't had a chance to isolate the specific part causing the issue.


 {{{
 SELECT ST_AsRaster(foo2.the_geom, rast1.rast, '1BB', 1.5, 1.5, false)
                                         FROM (
                         (SELECT
 ST_SetSRID(ST_SetValue(ST_AddBand(ST_MakeEmptyRaster( 100, 100, (i-1)*100,
 (i-1)*100, 0.0005, -0.0005, 0*i, 0*i), '16BSI'), i, (i+1),-6000),4326) As
 rast
                                 FROM generate_series(1,10) As i)
                  ) As rast1 CROSS JOIN ((SELECT
 ST_Buffer(ST_SetSRID(ST_Point(i,j),4326), j*0.05)  As the_geom
                 FROM (SELECT a*1.11111111 FROM generate_series(-10,50,10)
 As a) As i(i)
                         CROSS JOIN generate_series(40,70, 20) As j
                         ORDER BY i, i*j, j)) As foo2
                                         LIMIT 1;
 }}}

 Give me this error:
