--- Comment #25 from Arnd Bergmann <arnd at linaro dot org> --- (In reply to Arnd Bergmann from comment #24) > Created attachment 42194 [details] > r234568 ported to gcc-5 > > I ran into this old bug again while build testing with gcc-4.9.4 and > gcc-5.4.1.

Nevermind, that patch was incomplete, out of the two build failures I saw, one was fixed with this patch, the other one was not.
