Am seeing it locally, so that’s unnecessary. 

I don’t know. I thought initially it was because
unicode-error-sequence-regexp-range included non-character values in its
numeric range; but editing regex.c to avoid that doesn’t help. The failure
that provokes the error message is that dy->largest is 5 while dy->max is
four; however right up to dump time and beyond, dy->max is eight, it’s only
on loading the dumped data that it becomes 4. If I explicitly overwrite
Vthe_lisp_rangetab with an empty range table before dumping, the build
continues; but as far as I can work out this a bug in the dump process.
Marcus, you’ve worked with this pretty closely; any ideas?

(This patch makes the build continue with the current unicode.el:)

On the quay of the little Black Sea port, where the rescued pair came once
more into contact with civilization, Dobrinton was bitten by a dog which was
assumed to be mad, though it may only have been indiscriminating. (Saki)
