[fpc-pascal] FPC2.6 failed to raise compiler error "Argument can't be assigned to' for Generic class' Record property in "With" clause

[Dennis Poon]

I think I found a bug in FPC 2.6.2.
In a method of a derived specialized class, the compiler does not raise 
error (which it should)
With "record property" do
   "record property's field" := NewValue   //it should raise error 
since it is a record property and should not be allowed to modify just 
one  field.

Please see below sample code for reproducing the error:

Type

  RDevice=record
    Value : String;
    UpdatedAt : TDateTime;
  end;

  generic TGData <TData> =class(TComponent)
  private
    FData :  TData;
  public
    property Data : TData read FData;
  end;



  TDevice = class(specialize TGData<RDevice>)
  published
    procedure Test;
  end;

implementation

procedure TDevice.Test;
begin
  With Data do
    Value := ''; //no Compiler Error raised !!!
  Data.Value := ''; //Compiler raised "Error Argument can't be assigned to"

end;
