It's already the second time you warn me about this. Should I be

Actually I used a patched version for months in several projects
without issues. I replaced the kern with an hskip. That said, it's
unlikely that *I* will run into issues. And I'm curious about an
example where this fails and yields unacceptable results (like the
unpatched version does).

Thanks Hans for taking the time to look into that.
