--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Starting in GCC 11, we try to prop the add into the mem but then fail with:
```
cannot propagate from insn 9 into insn 10: would create an invalid MEM
cannot propagate from insn 9 into insn 16: would create an invalid MEM
```

I wonder if the mem address gets simplified or not ...
