Just to say, after further reviewing the logic in zmbv_me() and block_cmp(), I think it all tenuously holds together, with no possibilities of incorrect xored values or undefined behaviour. But it is quite fragile.

I’m planning some patches to strengthen/clarify the logic, and to make it more resilient to future changes, but I think this patch is good to go, as it is now.

Kind regards
