>   Bug#48729 SELECT ... FROM INFORMATION_SCHEMA.ROUTINES causes memory to grow
>   Analysis showed that in case of accessing I_S table
>   ROUTINES we perform unnecessary allocations
>   with get_field() function for every processed row that
>   in their turn causes significant memory growth.
>   the fix is to avoid use of get_field().
