--- Comment #9 from David Krauss <potswa at mac dot com> --- I didn't send it to gcc-patches. It's never been necessary for me before. I suppose I can collect the examples here into a testcase file. In the meantime, anyone else is free to take charge and submit it on their own. The change is just a matter of "don't do that."
