--- Comment #12 from Paolo Carlini <paolo.carlini at oracle dot com> ---
I'm having another look at this, and the last comments added to DR1584 and
coming to the conclusion that gcc probably doesn't need further work, in
particular the patch that I had to revert pointed to a real issue. Other
comments?
