[xml] xmlParseMemory core dump

[Rygg Christian Ingemann <christian ingemann rygg edb com>]

I am using TCP/IP to send XML from one computer to another, as a string of
characters. I then parse it using xmlParseMemory. Unfortunately I have a
small bug in my communication, so sometimes the end of the XML string is
lost, and I call xmlParseMemory with bad XML (Cut short). This makes the
program crash (core dump). Is it "supposed" to be like that, that bad XML
causes a core dump? If so, is there a function I can send the string through
first to check if it is OK? The XML looks like this when it's cut short:

<?xml version="1.0" encoding="UTF-8"?>

I realise the communication problem is the real problem, but it would be
nice to not have the program core dump :)
