The compiler skips reporting errors located in function expressions. After this patch the error is reported in the following sources:
package Base is type Base_Type is tagged record V : Integer; end record; function Func_1 (B : Base_Type) return Integer is (B.V); end; with Base; package DB is type DB_Type is new Base.Base_Type with record Y : Integer; end record; overriding function Func_1 (B : DB_Type) return Integer; private function Func_1 (B : DB_Type) return Integer is (Base.Func_1 (Base_Type (B)) / 8 * 4); -- Error end; Command: gcc -c db.ads Output: db.ads:13:20: "Base_Type" is not visible db.ads:13:20: non-visible declaration at base.ads:2 Tested on x86_64-pc-linux-gnu, committed on trunk 2017-09-08 Javier Miranda <mira...@adacore.com> * sem_ch8.adb (Find_Direct_Name.Undefined): Do not add entries into the undefined reference table when we are compiling with errors ignored.
