--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note `-g` here is important.

      /* There a no further out-of-loop uses of lhs by LC-SSA construction.  */
      FOR_EACH_IMM_USE_STMT (use_stmt, imm_iter, lhs)
        gcc_assert (flow_bb_inside_loop_p (loop, gimple_bb (use_stmt)));

I suspect:
```
  # DEBUG si1 => g_173.6_23
```

Or a slightly different one is not being updated.
