Need to create a memory leak

Hi.

This might be a strange request, but does anyone have any idea on a simple shell script that would use more and more memory as it ran? Like a purposeful leak.

I want to test the behaviour of an already running program when the machine runs out of memory.

Thanks!

Write a small C program which continuously loops and mallocs a chuck of memory each time.

Code:
#!/bin/sh
while (true) do
$0
done

Bad. Idea. That's not a memory leak, that's a fork bomb.

In perl,

keep the reference count greater than 0
Code:
my $hash_ref;
{
    my %check = (
                            abc => def
                         );

    $hash_ref = \%check;
}
