* exp_attr.adb (Expand_Attribute_Reference, case 'Read):
If the type is an unchecked_union, replace the attribute with
a Raise_Program_Error (rather than inserting such before the
attribute reference) to handle properly the case where we are
processing a component of a larger record, and we need to prevent
further expansion for the unchecked union.
(Expand_Attribute_Reference, case 'Write): If the type is
an unchecked_union, check whether enclosing scope is a Write
subprogram. Replace attribute with a Raise_Program_Error if the
discriminants of the unchecked_union type have not default values
because such a use is erroneous..
