Give it a try! Yes, I was using stock 4.8.1. And indeed this change seems to fix it. Thanks!

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58426 --- Comment #3 from Jan-Benedict Glaw jbg...@lug-owl.de --- Hm, the initial PLUS part looks a bit like what I ment to fix with a recent patch. How old is your checkout? My fix was committed as r202600 / git:3719e41cf6b9d. So I hope I didn't break something else. (This showed up in GIT at Sun Sep 15 09:44:29 2013 +.)
