--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Without a name on the struct, a becomes a local variable.
There is no aliasing issue here.
You can see the same effect in C via using:
```
static struct b1 { char elt1; char bits; } *a;
```
Since a does not have an address taken, GCC assumes (correctly), it will only
be modified from bar and will NOT be modified from an other variable/address.
