[Libxmlplusplus-general] Bug in SaxParser::parse_stream?

[Fredrik A. <e97_far@e.kth.se>]

Hello,

I think I have found a bug in SaxParser::parse_stream (saxparser.cc)
in libxml++ 0.17.0. This code:

  if( ! _exception )
  {
    exception * tmp = _exception;
    _exception = 0;
    tmp->Raise();
  }
  
will either do nothing at all or try to follow a null pointer.

I have attached a patch for what I think was intended.
