Can't determine which overloaded function to call for override constructor

Original Reporter info from Mantis: hnb

Description:

Can't determine which overloaded function to call for override constructor. In Delphi all is ok. I see no reason for that error (now to compile example I need to reimplement all constructors from TA - in normal code this is a big problem!):

---program---
{$MODE DELPHI}

type
  TA = class
  public
    constructor Create(A: Integer = 0); virtual; overload;
    constructor Create(A: string); virtual; overload;
  end;

  TB = class(TA)
  public
    constructor Create(A: string); override;
  end;

constructor TA.Create(A: Integer);
begin
end;

constructor TA.Create(A: string);
begin
end;

constructor TB.Create(A: string);
begin
end;

var
  B: TB;
begin
  B := TB.Create; // Error: Can't determine which overloaded function to call
end.
