--- Comment #4 from alalaw01 at gcc dot gnu.org ---
I confirm the testcase fails execution on armeb-none-eabi (also at -O0), but it
does so both with and without the patch to tree-scalar-evolution.c, which did
not change codegen (at -O2 -ftree-vectorize; the loop was not vectorized). So
this looks to be exposing a different, pre-existing, bug.
