--- Comment #5 from Robin Dapp <rdapp at gcc dot gnu.org> ---
I was about to say that I'm having trouble reproducing this one on rv32, both
the original test as well as the reduced one.

But it looks like it's only failing with newlib?  Odd, how would newlib affect
vectorization?  I'll investigate tomorrow.
