And that is precisely the reason why I think binding a reference to the
whole object or any of its members, when the object itself is a member
of a packed object, is illegal, hence requiring a diagnostic (unless,
like for both other cases, the default is to pack structures).
Doing that will break
struct Foo { void operator=(Foo const &);};
struct Baz __attribute__((packed))
{
char c;
Foo m;
}
void Bar (Baz *ptr)
{
ptr->m = something;
}
This is something we need to make work.
If your system packs structs by default, you should not be getting the
warning
on any of the uses.
But I do, and if I use a native Linux compiler with -fpack-struct, I
also get it (along with a second one on one of the two other
instances).
Then I think you have a bug.
