Need some resident memory usage? This cpp file constantly allocates sizeof(uint64_t)+sizeof(void*) of it and tries to keep it out of swapped memory.

hog.cpp

#include <stdint.h>
#include <stdio.h>

struct node_t {
	node_t() : i(0), previous(0) {}
	node_t(node_t *previous) : i(previous->i + 1), previous(previous) {}

	uint64_t i;
	node_t *previous;
};

int main() {
	node_t *last = new node_t();
	while(1) {
		last = new node_t(last);
		if((last->i % 10000) == 0) {
			printf("%8lu", last->i);
			node_t *current = last;
			while(current->previous != 0) {
				current = current->previous;
			}
			printf("\n");
		}
	}
