It is good to know Ada does this as well so that maybe us Ada/Pascal people can get together and come up with a fix. I submitted code that demonstrates this with my bug report as well....

The thread http://sources.redhat.com/ml/gdb-patches/2001-07/msg00714.html is probably relevant. Following on Joel's strategy (Ada) the first thing needed is probably a testcase so that people know the status of the underlying code Andrew From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: (qmail 5125 invoked by alias); 1 Feb 2002 12:29:36 -0000 Mailing-List: contact gdb-help@sources.redhat.com; run by ezmlm Precedence: bulk List-Subscribe: List-Archive: List-Post: List-Help: , Sender: gdb-owner@sources.redhat.com Received: (qmail 4888 invoked from network); 1 Feb 2002 12:29:32 -0000 Received: from unknown (HELO compc26.nc3a.nato.int) (195.169.112.86) by sources.redhat.com with SMTP; 1 Feb 2002 12:29:32 -0000 Received: from localhost.localdomain (localhost [127.0.0.1]) by compc26.nc3a.nato.int (Postfix) with ESMTP id 16FB413F39; Fri, 1 Feb 2002 13:32:11 +0100 (CET) Mail-From: gpc-owner+M403@gnu.de Sun Oct 14 15:28:28 2001 Message-ID: From: levi@localhost.nc3a.nato.int To: levi@localhost.nc3a.nato.int Cc: Maurice Lombardi , "Oldham, Adam" , gdb@sources.redhat.com, core@freepascal.org, gpc@gnu.de Subject: Re: GDB scope does not work quite right for Pascal Date: Fri, 01 Feb 2002 04:29:00 -0000 MIME-Version: 1.0 X-Mailer: Perl5 Mail::Internet v1.42 Content-Type: text/plain; charset="iso-8859-1" X-SW-Source: 2002-02/txt/msg00004.txt.bz2 Message-ID: <20020201042900.G0TcoHF9bMlmdqn5bJI2wf1BlrghjhwH-fsdCZklUQo@z> Yes, I saw some of these threads, but nothing seemed to shed light on fixes for the scoping of this.
