Just wondered if anybody had a good reason that this block of code should run out of memory. After a couple of hours of adding debug statements to my code I found that the following xml structure will cause an out of memory error when printed, but can be printed with dumper. Any help is greatly appreciated! 
#!/usr/bin/perl
use XML::Simple;
use Data::Dumper;

my $xml = qq|<?xml version="1.0" standalone="no"?>
<!DOCTYPE document SYSTEM "whocares.dtd">
<document>
    <QuestionList>
        <Question>
            <Id>3</Id>
            <Text>Are dingos your friend?</Text>
            <Answer>Satisfactory</Answer>
        </Question>
    </QuestionList>
    <QuestionList>
        <Question>
            <Id>11</Id>
            <Text>Should this run out of memory?</Text>
            <Answer>No</Answer>
        </Question>
    </QuestionList>
</document>|;

my $xml_ref = XMLin($xml);

print $xml_ref->{'QuestionList'}->{'Question'}->[0]->{'Answer'};
