Here's one that works for me:

    src/emacs -Q -l ~/tmp/foo.el -f my-test

where `foo.el` is the attached file.

Then scroll horizontally (I use `C-f` from the BOL and `C-b` from EOL to
do that), you'll see that sometimes the columns aren't aligned (tho
sometimes they are, even the very same columns).
