[libxml++] memory leak in SaxParser

[thierry <thi...@di...>]

I have encountered a memory leak (not signalized by Purify) in the class =
SaxParser.
in the function parse() :

"_context->sax =3D & _sax_handler;

[..]

release_underlying();"

is not valid. structure allocated in xmlCreateMemoryParserCtxt for the =
sax handler is never released due to=20

"_context->sax =3D 0 " in release_underlying().

The solution I have found was to use memcpy and to really release sax =
object of context.

I don't how to make patch so this is how looks my corrections in parse

void SaxParser::parse(){

if(!_context) throw internal_error("Parse context not created.");

//_context->sax =3D & _sax_handler;

memcpy(_context->sax, &_sax_handler, sizeof(xmlSAXHandler));

_context->userData =3D this;

initialize_context();


xmlParseDocument(_context);

if( (! _context->wellFormed)

&& (! _exception) )

_exception =3D new parse_error("Document not well-formed");

//release_underlying();

xmlFreeParserCtxt(_context);

_context =3D 0;

check_for_exception();

}
