#1659: ST_Union raster out of memory then kicks the bucket on windows 64bit

     Type:  defect                      |      Status:  new          
 Priority:  medium                      |   Milestone:  PostGIS 2.0.0
Component:  postgis                     |     Version:  trunk        
 Keywords:  mingw windows 64bit, 32bit  |  
----------------------------------------+-----------------------------------
 I ran this test on my mingw32 build (on PostgreSQL windows 32-bit on
 windows 7 64-bit) and my mingw64bit (on PostgreSQL windows 64-bit windows
 2003).


 {{{
 SELECT ST_AsEWKT(ST_ConvexHull(ST_Union(rast1.rast, 1))) 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 LIMIT 3;
 }}}

 On my postgsi 32 bit it gives error

 {{{
 NOTICE:  Neither raster provided has a NODATA value for the specified band
 indices.  NODATA value set to minimum possible for 16BSI
 CONTEXT:  PL/pgSQL function "_st_mapalgebra4unionstate" line 13 at RETURN

 ERROR:  out of memory

 }}}

 on the 64-bit build it gives


 {{{

 indices.  NODATA value set to minimum possible for 16BSI

 }}}

 Then just kills the service.
