self-contained test case, compilable as C and C++
The wrong-code reproduces for me with gcc 4.7 and 4.8 on x86_64-linux. For
trunk it was fixed by r204515, which doesn't appear to be a wrong-code fix.
Backporting r204515 to 4.8 fixes the wrong-code there too, but I haven't tested
it beyond this test case.
