Description:
------------
When parsing a XML document without a prolog PHP5 seems to "freeze", never returning from xml_parse and never calling the call backs. This is reproducible on both Debian/PHP 5.0.2 with libxml 2.6.11 and Mac OS X/PHP 5.0.3 with libxml 2.6.7
I've attached the simplest possible example to demonstrate this (probably best to run it from the command line, but the problem is reproducible running under Apache and from the command line)
Reproduce code:
---------------
<?php
$xml1 = '<?xml version="1.0"?><greeting>hello world</greeting>';
$xml2 = '<greeting>hello world</greeting>';
$parser = xml_parser_create('');
xml_set_element_handler($parser, "startElement", "endElement");
$status = xml_parse($parser, $xml1, true);
function startElement($parser, $name, $attrs) {
echo "start $name\n";
}
function endElement($parser, $name) {
echo "end $name\n";
}
?>
Expected result:
----------------
I would expect to see the program echo "GREETING", and then end. This is what happens when you run this same script under PHP4
Actual result:
--------------
It just sits there until you kill it.

Verified on Linux with libxml-2.6.16. Seems like a libxml bug to me. Program received signal SIGINT, Interrupt.
