Ahah -- when I try this with a 120MB file, I get non-random miscompares!

Out of 12 tests,
it compared OK once. It broke at byte 1365812 four times 24542708 twice 2195188 twice three different place once each
This does seem to point the finger at a software problem. Anyway, we'll try 2.0.36 and see what happens.
