[fpc-devel]Delphi incompatibility/error (DynArray) in 1.1

[Morten Juel Skovrup]

I think I've found a couple of Delphi incompatibilities in branch 1.1
(snapshot 09/01/03) (- couldn't find anything in the buglist) - one
compiler related, and one which generates a runtime-error - see the
following source.

program TestFPC11;

type
  TDoubleArray = array of Double;
  TTestProp =
    record
      TestItem : Double;
    end;
  TTestPropArray = array of TTestProp;

  TTestClass =
    class
      private
        FTestProp: TTestPropArray;
      public
        constructor Create;
        destructor Destroy; override;
        property TestProp : TTestPropArray read FTestProp;
    end;

procedure Init(var AnArray : array of Double);
var
  i : Integer;
begin
  for i:=0 to High(AnArray) do
    AnArray[i] := 1;
end;

var
  Test      : TDoubleArray;
  i         : Integer;
  TestClass : TTestClass;

constructor TTestClass.Create;
begin
  inherited Create;
  SetLength(FTestProp,2);
end;

destructor TTestClass.Destroy;
begin
  Finalize(FTestProp);
  inherited Destroy;
end;

begin
  SetLength(Test,5);
  Init(Test);                       //!!! FPC compile error - Delphi
compiles fine...
  for i:=0 to High(Test) do
    WriteLn(Test[i]);
  Finalize(Test);

  TestClass := TTestClass.Create;
  with TestClass.TestProp[1] do     //!!! FPC stops with runtime-error

    TestItem := 2;
  WriteLn(TestClass.TestProp[0].TestItem);
  WriteLn(TestClass.TestProp[1].TestItem);
  TestClass.Free;
end.
