--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue here is that we have a load group with one stmt feeding a condition.
For some reason we think that we can support vectorizing
_7 = _4 != 0
with _4 being defined by a pure-SLP def. Which looks odd - the this is clearly
not a pure SLP node!
Fix:
