Thanks, I reproduced this, and will look into it in a couple of days,
if no one beats me to it.

Not exactly: it hits assertion violation on this line:

		start_byte = CHAR_TO_BYTE (start);

whereas your original report did that here:

            ceiling_byte = min (CHAR_TO_BYTE (next_change) - 1, ceiling_byte);

But it's probably the same problem, so this recipe should be good
enough for starters.
