Yes, I can see it, it seems correct.

The test suite runs with LC_ALL=C already, this is not needed.

So it may well be that the problem is actually the perl snippet I
used to "reveal" the invalid characters.  Please try this:

$ printf "\0\n" > /tmp/foo.y
$ LC_ALL=C ./src/bison -fcaret /tmp/foo.y >/tmp/foo.log 2>&1
$ perl -p -e 's{([\0\377])}{sprintf "\\x%02x", ord($1)}ge' /tmp/foo.log
/tmp/foo.y:1.1: error: invalid character: '\0'
    1 | \x00
      | ^


Cheers!
