This patch fixes the handling of extension aggregates when the parent type is a private extension that constrains a discriminant of the parent. The following must compile quietly: with P; use P; package X is type Base_I is interface; type Interface_And_Child is new Child_1_3 and Base_I with null record; function Copy_No_Clone (Object : Interface_And_Child) return access Interface_And_Child; type Interface_And_Child_Acc is access all Interface_And_Child'Class; end X; --- package body X is function Copy_No_Clone (Object : Interface_And_Child) return access Interface_And_Child is Res : Interface_And_Child_Acc := new Interface_And_Child'(Child_1_3 with others => <>); begin return Res; end Copy_No_Clone; end X; --- package P is type Root_1 (V : Integer) is tagged null record; type Child_1_3 is new Root_1 (1) with private; private type Child_1_3 is new Root_1 (1) with null record; end P; Tested on x86_64-pc-linux-gnu, committed on trunk 2010-06-17 Ed Schonberg <schonberg@adacore.com> * sem_aggr.adb (Valid_Ancestor_Type): handle properly the case of a constrained discriminated parent that is a private type. (Analyze_Record_Aggregate): when collecting inherited discriminants, handle properly an ancestor type that is a constrained private type.
