However, the patch is applied to trunk only for now. I wasn't going to backport it to gcc-5 because 64411 doesn't have any mentions of the compiler that works. But for this test my system opensuse gcc works. Thus it can be classified as a regression, and I would backport it to gcc-5 branch and add also this test case to trunk and gcc 5.
