But it is empty, therefore there must be some other reason
for what you see.

I've had a look at those and can't see anything strange.

I noticed that the contours are generated with a very much earlier
version of mkgmap, before r1003.  Is there any possibility that
the problem goes back that far (mid April), as that changed
values that we don't really understand?

It would be easier if you could pin down the version where it
changed more precisely.
