--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. we start out with:
```
  __builtin_memcpy (&a, &MEM <int> [(void *)&b + -1B], 2);
  _4 = MEM[(char * {ref-all})&b];
  MEM[(char * {ref-all})&a] = _4;
```

And DSE converts it into:
```
  __builtin_memcpy (&MEM <char> [(void *)&a + 1B], (char *) &b, 1);
  _4 = MEM[(char * {ref-all})&b];
  MEM[(char * {ref-all})&a] = _4;
```
