Hi all.
At Mantis Florian already explained, why it is not possible to provide
more information in the error message. Still he meanwhile managed to
make it better. I got some time to return to this and now I'm here:
17:11 myn...@tux64:~/fpc/bugreports/20100105$ cat project1.pas
program project1;
{$mode objfpc}{$H+}
uses
fgl;
type
TPar = record
I: Integer;
end;
operator = (A, B: TPar): Boolean;
begin
Result := A.I = B.I;
end;
type
TSpec = specialize TFPGList<TPar>;
begin
end.

I'm now able to track the source of the error message to line 715:50
of rtl/objpas/fgl.pp:
711 function TFPGList.IndexOf(const Item: T): Integer;
712 begin
713 Result := 0;
714 {$info TODO: fix inlining to work! InternalItems[Result]^}
715 while (Result < FCount) and (PT(FList)[Result] <> Item) do
716 Inc(Result);
717 if Result = FCount then
718 Result := -1;
719 end;
Still I'm stuck and don't know how to use items like TPar in the
specialization of TFPGList - or if it is a compiler bug.
Thanks in advance for anyone's help/explanation/hint.
