You still need to call XML_ParserFree.
XML_ParserReset just allows you to re-use
the same parser instance for additional runs.

In any case, your use of abort() would produce
memory leaks anyway, since XML_ParserFree would
not get called in that case.

I recommend you check the HTML documentation
(reference.html) which has some sample code
for the main parsing loop.
