Subject: [COMMITTED] ada: Add missing guard to previous change
Date: Tue, 19 Dec 2023 15:30:37 +0100 [thread overview]
Message-ID: <20231219143037.455041-1-poulhies@adacore.com> (raw)
From: Eric Botcazou <ebotcazou@adacore.com>
Ancestor_Type is overloaded with Aggregate_Bounds on N_Aggregate nodes
so its access needs to be guarded in Copy_Generic_Node.
gcc/ada/
* sem_ch12.adb (Copy_Generic_Node): Add guard for Ancestor_Type.
Tested on x86_64-pc-linux-gnu, committed on master.
