Strange, absolutely same output:
$ printf "\0\n" > /tmp/foo.y
$ LC_ALL=C ./src/bison -fcaret /tmp/foo.y >/tmp/foo.log 2>&1
?1$ xxd /tmp/foo.log

$ perl -p -e 's{([\0\377])}{sprintf "\\x%02x", ord($1)}ge' /tmp/foo.log

In case you are not happy with debugging this case (and I would
understand it) is there a way how to disable it?
Otherwise I am fine to assist you in digging further. Any other hint,
please?
Thank you
