* sem_util.adb (Is_Aliased_View): Defend against the case where this
subprogram is called with a parameter that is not an object name. This
situation arises for some cases of illegal code, which is diagnosed
later, and in this case it is wrong to call Is_Aliased, as that might
cause a compiler crash.
(Explain_Limited_Type): Refine previous fix to include
inherited components of derived types, to provide complete information.
* exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
is the prival for a protected object.
It is necessary to mark this entity as a variable, in addition to
flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
modified to avoid checking the Aliased flag on entities that are not
objects. (Checking that flag for non-objects is erroneous and could
lead to a compiler crash).
