Buffer too small for string - Crystal Report for Vs2010

Question

Hello,
    I have recently upgrade my VS2010 project to Crystal Report for Visual Studion 2010.
    I have some reports that contains more than 512 characters in the Report Comments section.
    When I try to do a RptDoc.SaveAs(vPath, false) the following error is raised:
Buffer too small for string or missing null byte.
      at CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass.SaveAs in :line 0
      at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.SaveAs in :line 0
      at CrystalDecisions.CrystalReports.Engine.ReportDocument.SaveAs in :line 0
    This line SaveAs was working has expected with Crystal Report 2008. Any idea on why it is not working anymore.
Thank you.
Charles

Hello Don,
    I have start a little project to retest the behavior.
   I have create a new report in Crystal Report 2008 just by clicking New, Finish and Save.
   In a new Windows Application in Vs2010 ,I have added the following Crystal Report Reference.
    CrystalDecisions.CrystalReports.Engine, Version=13.0.2000.0
   CrystalDecisions.Shared, Version=13.0.2000.0
I have then try the following code and found out the limit of ReportComment is 511 but in the Crystal Report 2008 designer and runtime the limit did not apply.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
      Dim objRpt As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
      Dim i As Integer = 0
      Try
         objRpt.Load("c:\temp\empty.rpt", CrystalDecisions.Shared.OpenReportMethod.OpenReportByTempCopy)
         Do
            i += 1
            objRpt.SummaryInfo.ReportComments = New String("X", i)
         Loop
         objRpt.SaveAs("c:\temp\dfh_save.rpt", False)
      Catch ex As Exception
         MsgBox("i: " & i)
         MsgBox(ex.Message)
      End Try
End Sub
     I am able to put has many characters if I insert the report in the Vs2010 Solution.
     If you prefer I can send you my little project.
Thank you.
