rasql - segfault with binary operator from 2 decoded files with multiple bands

[Bang Pham Huu]

This decode() + decode() operator works with mr file with 1 band:

SELECT encode(decode(<[0:0] 1c>, "GDAL", "{\"filePaths\":[\"/home/rasdaman/rasdaman_community/rasdaman/systemtest/testcases_services/test_all_wcst_import/testdata/wcps_mr/mr_1.png\"]}") + decode(<[0:0] 1c>, "GDAL", "{\"filePaths\":[\"/home/rasdaman/rasdaman_community/rasdaman/systemtest/testcases_services/test_all_wcst_import/testdata/wcps_mr/mr_1.png\"]}"), "png")

but segfault with rgb file with 3 bands:

'SELECT encode(decode(<[0:0] 1c>, "GDAL", "{\"filePaths\":[\"/home/rasdaman/rasdaman_community/rasdaman/systemtest/testcases_services/test_all_wcst_import/testdata/wcps_rgb/rgb.png\"]}") + decode(<[0:0] 1c>, "GDAL", "{\"filePaths\":[\"/home/rasdaman/rasdaman_community/rasdaman/systemtest/testcases_services/test_all_wcst_import/testdata/wcps_rgb/rgb.png\"]}"), "png")'... parsing... checking semantics... evaluating...

It looks like duplicate to #2377 (yes it's a different query but same issue with multiband).
