It's probably a bug in your program.

If your compiler stores ints in 16 bits, then 65536 is a long
and 65536/512 is also a long.  You should therefore do one of the
following:

	printf("This should work : %d, %d\n", (int)(65536/512), 512);
	printf("This might also work : %ld, %d\n", 65536/512, 512);
