Surprise! That one does contain \x00 and the above perl line works
like charm:
dam@unstable10s
[unstable10s]:/home/dam/mgar/pkg/bison/trunk/work/solaris10-sparc/build-isa-sparcv8plus/bison-3.7.90
> perl -p -e 's{(\0|[\200\210\360\377])}{sprintf "\\x%02x", ord($1)}ge' <log
./tests/testsuite.dir/004/input.y:1.11: error: invalid null character
1 | %header "\xf0\x00\x80\x88"
| ^
and also this one:
dam@unstable10s
