Very Strange problem in BatchSend

Hello AB,

I have a very strange problem, when I try to use batchSend and send 7 records, BatchSend resturns error 400, If I try to send 6 or 8 records then Works Ok!!!
I Have the particulary that the SQLRecord has 82 Fields, so I have to change the MAX_SQLFIELDS to 128.

The Problem is in Delphi 7 and also in Delphi XE7U1

This is the sample code to reproduce the problem

// SQL Model

  TPerson = class(TSQLRecord)
  private
    fField39: RawUTF8;
    fField81: RawUTF8;
    fField80: RawUTF8;
