> message:
>   Bug#45152 crash with round() function on longtext column in a derived table
>   The crash happens due to wrong max_length value which is set on
>   Item_func_round::fix_length_and_dec() stage. The value is set to
>   args[0]->max_length which is too big in case of LONGTEXT(LONGBLOB) fields.
>   The fix is to set max_length using float_length() function.
