--- Comment #18 from vehre at gcc dot gnu.org --- Yes, it also fixes the ICE in #11. The code example is part of the regression test added. I hope you don't mind. Most parts of the regression test added base on your reported issues. Additionally the whizard code mentioned in #1 is compiling and running again.
