Server killed with condenser count_cells

[Bang Pham Huu]

it works if select 1 band from 3 bands collection

rasql -q 'SELECT encode(MARRAY n in [0:255] 
VALUES  count_cells(c.0 = n[0]) , "text/csv" ) 
FROM test_rgb AS c'

but without specific 1 band, server killed

'SELECT encode(MARRAY n in [0:255] VALUES 
 count_cells(c = n[0]) , "text/csv" ) 
FROM test_rgb AS c'...
