* sem_ch6.adb (Check_Private_Overriding): Refine the legality

overriding SOMEthing. Now it checks that the function is
overriding a corresponding public operation. This is a correction

call to String'Input, returning a dynamically sized value on the
secondary stack) will be expanded outside of proper secondary
stack mark/release operations, and will thus cause a secondary
stack leak.
