> Adding "const" makes it compile. Is this the intended behavior or not?
Yes, of course. A const-reference causes a temporary to be created, you didn't
bind to the packed field:
Squeeze oj;
oj.s = 0;
const short& pit(oj.s);
oj.s = 1;
printf("%d %d", oj.s, pit);
This shows that oj.s and pit are not the same variable.
