Hmm, shouldn't both the actually applied size and the true size be displayed?
e.g.

ret=0x5 (in 8 bytes, true size: 16 bytes)

I have to ask. Why do we care? Is there a use for this information?

If the structure itself is being returned, representing it as a scalar
value could lead to misunderstandings. Since we can check it is a
scalar or not, it should be noticed. In this meaning, I think "(trunc)"
is also good to me. (at least user can notice it)

Thanks,

If not, ret=0x5 would be sufficient.
