  The real crash point is not inside the method
  XML_ODH_Query_Execution, instead it is inside method
  XML_ODH_Xalan_Interface.  This relates to memory management.
  While allocating memory through the new operator, the default
  compiler allocates memory at high address and while referencing
  this memory, the instance crashes.
