This don't happen on v3.18 so in that sense Peter's patch is kind of half-regression fix for v3.19.
What's new in v3.19 is that the kernel will shout if it encounters such a invalid route, previously it was just silently ignored. But either way it never actually worked, so it's not really a v3.19 regression.
