More identifier redeclaration error problems - Gpc

8 Jan 2006


      It looks like the "20050325: check identifier scopes stricter" bug fix
didn't completely solve all the identifier redeclaration error problems
involving an applied occurance of an outer scope identifier in an inner
scope with a defining occurance of the identifier.  The following two
test programs will compile and run with the latest GPC version which
shows that GPC still has a few problems with detecting redeclaration
errors in scopes involving record type-denoter and formal-parameter-list regions.
{$extended-pascal}
program gale7 (output);
type
  t = record
    case integer of
      0: (boolean : boolean)  {WRONG}
      otherwise (f : integer)
    end;
begin
writeln('FAIL');
end.
{$extended-pascal}
program gale8 (output);
type
  t = integer;
procedure foo(t: t);  {WRONG}
begin
end;
begin
writeln('FAIL');
end.
The compiler I used was the latest version of Mac OS X GPC that Adriaan
built and made available for downloading  few weeks ago.  The specs:
