You are right, I somehow confused things, and log is incorrect. So it's not
the test suite which is wrong, but bison itself.
There remains one last check to make sure it's bison the binary that is wrong:
LC_ALL=C ./src/bison ./tests/testsuite.dir/004/input.y 2>/tmp/log
(src/bison, not tests/bison)
But I'm pretty sure the \x00 is still not there, and it's going to painful to
diagnose and fix :( Yet this rings some bell, I'll dive into the history to
find something similar.
