I get the same XML::Simple behavior as you. I got tired of waiting for the program to end and broke it. That put my machine into a wierd state and I was forced to reboot. (damn win2k).
I then wrote a little XML::SAX routine to see what was happening (see below). Doesn't XML::Simple and XML::SAX both use XML::Parser under the hood? Anyways, I appears that once it gets to the data element the character sub gets called once for each line of data, 76 chars, and then once again for each newline. This continues for some time, but it does finish with the data element containing 8786162 chars.

use strict;
use warnings;
use XML::SAX;

my $h = Handler->new();
my $p = XML::SAX::ParserFactory->parser(Handler => $h)
    or die "Unable to get XML SAX parser object";
$p->parse_uri("10.xml");

BEGIN {
package Handler;

sub new {
    my $class = shift;
    bless({chars => ''}, ref $class || $class);
}

sub start_element {
    my ($this, $data) = @_;
    $this->{chars} = '';
    print "start $data->{Name}\n";
}

sub end_element {
    my ($this, $data) = @_;
    print "end $data->{Name} = ", length($this->{chars}), "\n";
    $this->{chars} = '';
}

sub characters  {
    my ($this, $data) = @_;
    my $chars = $data->{Data};
    $this->{chars} .= $chars;
    print "characters ",length($chars),"\n";
}
}
