Internal error 200510032 for inline methods that have not been inlined

Original Reporter info from Mantis: deep42thought

• Reporter name: Erich Eckner

Description:

When compiling the test program (this is a reduced program from my original program - maybe, there is a simpler version to trigger the error, but I could not find one in a greedy way) in objfpc mode, internal error 200510032 is raised. This can be fixed by removing "inline" from any of the mentioned methods. Strangely, when making "count" non-inline or when changing the output type of minMaxY from tPoint to integer raises some strange linker error instead (so I assume, the internal compiler error is also gone, but I cannot be sure about that).

fpc is a custom build, but it's pretty straight-forward (it uses mainly the build instructions from arch linux):

P.S.: there is no version 3.2.0 in the drop-down for the "product version"

Steps to reproduce:

cat >test.pas <&LtPos;EOF
program test;

{$mode objfpc}{$H+}

uses
  Classes, SysUtils;

type
  tMessPunkt = class
  private
    function rMW: integer; inline;
  public
    property mW: integer
      read rMW;
  end;

  tMessPunkteListe = class
  private
    function rItem(i: longint): tMessPunkt; inline;
  public
    function count: longint; inline;
    property items[i: longint]: tMessPunkt
      read rItem; default;
    function minMaxY: tPoint; 
  end;

function tMessPunkt.rMW: integer;
begin
  result:=0;
end;

function tMessPunkteListe.rItem(i: longint): tMessPunkt;
begin
  if i>=count then
    raise exception.create('i too large');
  result:=nil;
end;

function tMessPunkteListe.count: longint;
begin
  result:=0;
end;

function tMessPunkteListe.minMaxY: tPoint;
begin
  result.x:=items[0].mW;
  result.y:=items[0].mW;
end;

begin
end.

Additional information:

This seems to have worked with fpc 3.0.4 before, but I am not 100% sure about that.
