The internal design of the data structures used by cachegrind assumes that sizes will be powers of two and that it can compute indexes by bit masking. That is, as you have found, no longer true for modern processors, but to date nobody has stepped up to fix cachegrind. On top of that it isn't clear that there is a good fix that wouldn't produce a loss of performance.
