Oh, it was non-ASCII characters in the input file, and all would have been
well if it had failed cleanly with a reasonable error message in the parser,
but it didn't.

I'll look at relocating this code so as to do a first parse without
expansions of entity references, in order to not block use of such, but
still catch non-ASCII characters in files declared to be us-ascii.
