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!

sg_get_swap_stats

sg_get_mem_stats(3)					     Library Functions Manual					       sg_get_mem_stats(3)

NAME

       sg_get_mem_stats, sg_get_swap_stats - get VM statistics

SYNOPSIS

       #include <statgrab.h>

       sg_mem_stats *sg_get_mem_stats(void);

       sg_swap_stats *sg_get_swap_stats(void);

DESCRIPTION

       Memory statistics are accessed through the sg_get_mem_stats function. It returns a pointer to a static sg_mem_stats.

       The sg_get_swap_stats returns returns swap statistics. It returns a pointer to a static sg_swap_stats.

       On  the	FreeBSD  operating system elevated privileges are required to access the swap statistics. Making the program setgid kmem should be
       sufficient. Programs running as root will not have this problem.

RETURN VALUES

       The VM system calls can return a pointer to either a sg_mem_stats or a sg_swap_stats.

       typedef struct{
	       long long total;
	       long long free;
	       long long used;
	       long long cache;
       }sg_mem_stats;

       total  The total amount of memory in bytes.

       free   The total free memory in bytes.

       used   The total used memory in bytes.

       cache  The amount of cache used in bytes.

       typedef struct{
	       long long total;
	       long long used;
	       long long free;
       }sg_swap_stats;

       total  The total swap space in bytes.

       used   The used swap in bytes.

       free   The free swap in bytes.

TODO

       Add a function to hold open the file descriptor to the kernel memory structures. Doing this would  allow  the  elevated	privileges  to	be
       dropped early on.
