Give me till the end of the week: if I haven't solved it by then I will
probably have to give up and go on to other things anyway.
(FWIW, it seems to happen when encoding greater than 4 but less than 8
AES blocks - in particular with both 7 and 5 blocks encoded I can see it
go wrong from block 4 onwards. No idea why yet, and the asm is pretty
dense, but that's where I'm at at the moment.)
