--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  The alignment consideration shouldn't apply in this case - the
MyStruct object is either there or not.  Note

typedef struct {
    bool a[];
} MyStruct;

bool f(const MyStruct *s)
{
    return s->a[0] || s->a[1];
}

would be a different story.
