I don't have a strict alignment arch at hand, but this should do
it:

#include <sys/types.h>
#include <murmurhash2.h>
#include <stdio.h>

#define SIZE 10

int main(void)
{
	char a[SIZE+4];
	int i;

	for (i = 0; i < 4; i++) {
		printf("%d\n", i);
		fflush(stdout);
		murmurhash2(a+i, SIZE, 0);
	}

	return 0;
}
