Your example works fine for me too (except that it won't swallow the <<XML; ... XML construction, so I rewrote it).

However, it breaks if I have just one <lemma>-tag with many children. I find that the breaking point is at 4696/4697.

use warnings;
use strict;
use XML::Twig;

my $children = 4697;
my $found;
my $xmlStr = '<XML><lemma>'.join("\n",@{['<line>1</line>' x $children]
+}).'</lemma></XML>';

my $twig = XML::Twig->new(
    keep_encoding => 1,
    twig_handlers => {'lemma' => \&ProcessLemma}
    );

$twig->parse($xmlStr);
print "Expected one, found $found\n";


sub ProcessLemma {
    my ($XmlTwig, $XmlLemma) = @_;

    ++$found;
    $XmlLemma->purge;
    return 1;
}

Btw, I don't know if it matters, but I'm using Win32, ActivePerl 5.14.2.
