Description

This works: 

SELECT ST_MapAlgebraExpr(ST_AddBand(ST_MakeEmptyRaster(4, 4, 0, 0, 1, 1, 0, 0, -1), '32BF'::text, 6, -1), 1, 
                         ST_AddBand(ST_MakeEmptyRaster(4, 4, 0, 0, 1, 1, 0, 0, -1), '32BF'::text, 4, -1), 1, 
                         'rast1 + rast2'::text, 
                         NULL::text, 
                         'UNION'::text, 
                         NULL::text, 
                         NULL::text, 
                         NULL::double precision);

but this crashes: 

SELECT ST_MapAlgebraExpr(ST_AddBand(ST_MakeEmptyRaster(4, 4, 0, 0, 1, 1, 0, 0, -1), '32BF'::text, 6, -1), 1, 
                         ST_AddBand(ST_MakeEmptyRaster(4, 4, 0, 0, 1, 1, 0, 0, -1), '32BF'::text, 4, -1), 2, 
                         'rast1 + rast2'::text, 
                         NULL::text, 
                         'UNION'::text, 
                         NULL::text, 
                         NULL::text, 
                         NULL::double precision);

the only difference is a refer to a non existing band number in the second case.
