You are really great :-) By the way. Do you know a good Package for searching memory leaks under Windows XP and perl version 5.8.8. I have memory problems, although I use allways strict.pm (working only with local vars 'me $var') and have no global vars. The program has about 40000 Lines in 100 packages. I would like to have something like the symdump does to produce a list of all variables whose size has changed or are new allocated between two program-positions: 
   my $memdump = MemoryDump->new();

   anyFunction();

   print $memdump->diff(MemoryDump->new();

Exist something like that for ActiveState-Perl?

For your example which you've wrote for me: So if I set the size of the array @a 


my @a = ();

$#a = 1e6;

[download]

the memory will be used again 


my @a = ();

$#a = 1e6;

mem(1);

$a[ $_ ] = $_ for 1 .. 1e6;

mem(2);

undef @a;

mem(3);

my @a = ();
$#a = 1e6;

$a[ $_ ] = $_ for 1 .. 1e6;

mem(4);

sub mem {
    my $mem = `tasklist /nh /fi "PID eq $$"`;
    $mem =~ tr[ \t\n][   ]s;
    print "$mem : $_[0]\n";
};
