In trying to parse some very simple, but large XML files, I've found that XML::Simple hangs. The following example demonstrates the problem:

#!/usr/bin/perl
use warnings;
use strict;
use XML::Simple qw/XMLin/;

my $file = shift || die "Must supply xml file";
open FH, '<', $file or die "Cannot open $file for reading: $!";
my $document = do { local $/; <FH> };
XMLin($document);

You can down load a compressed (6.2 Meg) version of the XML that causes this to choke. The XML itself is rather simple. It's a huge base64 encoded mp3 that is causing problems. As near as I can tell, the actual problem is an infinite loop in XML::Parser::Style::Tree.

XML::Simple is the latest version and expat is 1.95.5.

Anyone seen this problem before? (Wrapping the base64 encoded data in a CDATA section has no effect).
