Re: [libxml++] memory leak in SaxParser

["thierry" <thierry blanchard digitech fr>]

at it is done in xmlSAXUserParseMemory...

I think this is the best solution.
Thank you for your immediate reaction.
Good luck

It seems I've spoken a bit fast sorry ;-) We can't do that. The functions I
spoke about don't return a context.

So we have to make sure either the sax handler can be freed by libxml,
either
handle it ourselves.
The proposed solution was not handling the same problem happening with
xmlCreatePushParserCtxt, that we use for parse_chunk and parse_stream, which
makes a copy of the sax handle we give to it, and this copy is never
released.
So I removed the reset of sax handler in release_underlying. In parse, I
just
save the defaut sax parser and restore after parsing, as it is done in
xmlCreateMemoryParserCtxt for example.

I think this correct the problem(s).

Cheers,

Christophe
