The following program takes an ever growing amount of memory, while the memory should be freed at each iteration. #! perl -w use strict; use XML::LibXML; for(my $i=0; $i<1_000_000; $i++){ my $entry = "<entry><sense></sense><sense></sense></entry>"; my $parser = new XML::LibXML; my $doc = $parser->parse_string($entry); my $root = $doc->getDocumentElement; my $g = 0; # The memory leak comes from the following line foreach my $sense (@{ $root->getElementsByTagName("sense") }){ $g++ } } Perl version: 5.6.1 XML-LibXML version: 1.40 Operating system: % uname -a Linux borel5.institut.math.jussieu.fr 2.4.2-2smp #1 SMP Sun Apr 8 20:21:34 EDT 2001 i686 unknown
