Whoops, this fell through the cracks - I can't reproduce with
g:7a4770f0394751860ee54520b23007938907ac33 though. Confirmed with your
cited rev. where we see

and thus a released SSA name. That's probably inconsistent SCEV cache
not reset before cunroll and the issue is probably still latent.
For curiosity I wonder what "fixed" it.
