--- Comment #9 from Marc Glisse ---
I was thinking that
struct __attribute__((packed)) A { int i; };
should be handled like
typedef int int_unaligned __attribute__((aligned(1)));
struct A { int_unaligned i; };
but it appears that for the aligned

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

All assignments of obj.s to type short and short* are incorrect, and ideally
they would all result in compiler errors.
The C++ spec (C++03, Sects. 3.9, 3.9.1, 3.9.2) are

compile:

{
short s;
} __attribute__((aligned(1), packed));
void VerticallyChallenged(short*) {}
