There is no way that auto_ptr can crash.  The crash has to be occuring
inside your TForm itself during its construction, probably during the
DFM streaming.  One of the controls is likely doing something it
shouldn't be doing.

One thing I just noticed in your earlier message is the following:

    __fastcall TForm2::TForm2(TComponent* Owner)
        : TForm(Owner)
    {
        StringGrid1->ColCount = 0;
        StringGrid1->RowCount = 0;
    }

You can't set the RowCount to zero.  TStringGrid requires at least 1
non-fixed row at all times.  Why Borland designed TStringGrid that
way, I have no clue.

Are you still using that code in your TSubForm?
