            Bug ID: 117876
           Summary: get_later_stmt used on stmts not in the same BB
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

The vectorizer uses get_later_stmt to order stmts only looking at UID but
UIDs are only comparable when the stmts are in the same BB (or there is
a total order with the particular RPO walk done when computing UIDs).
