PVS-Studio warning V505 for MultiThreadSimpleQueue

COleDataSource* CGridCtrl::CopyTextFromGrid()
{
  ...
  for (int row = Selection.GetMinRow();
    row <= Selection.GetMaxRow(); row++)
  {
    ...
    sf.Write(T2A(str.GetBuffer(1)), str.GetLength());
    ...
  }
  ...
}

This code is potentially dangerous. T2A() macro uses alloca() function. As alloca() function is called from within the loop, it can quickly lead to stack overflow.

This suspicious code was found in MultiThreadSimpleQueue project by PVS-Studio static code analyzer.
Warning message is:
V505 The 'alloca' function is used inside the loop. This can quickly overflow stack. GridCtrl  gridctrl.cpp  2332
