	* exp_attr.adb (Expand_N_Attribute_Reference, case Input): When
	expanding a 'Input attribute reference for a class-wide type,
	do not generate a separate object declaration for the controlling
	tag dummy object; instead, generate the expression inline in the

	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.
