I don't think so, but I'm not quite sure I understand. Anyhow, I'm sure
I don't have any uncontributed patches for this, and I don't think
Nathan has either.

I do not. I remember looking at it, but didn't get anywhere.

Yo!
Jason, fixing this would be most appreciated by the library hackers. This is
one of those things that I would really like to see implemented before C++0x
gets too far down the road... there is a bunch of stuff depending on this, from
both C++0x and TR1.
Also, I believe that the deprecated attribute issue is also related to some of
these issues.
Those bugzilla numbas are:

Yes, Gaby, the issue at large is clear, by now: see c++/17743. Here, we are
just trying to achieve *minimal* functionality, when the espression in the
attribute is not dependent: among other things (currently __align__ inside
templates is *totally* broken :( this would allow me to provide a decent first
implementation of aligned_storage via specializations for Align=1,2,4,8,16
There is an updated patch ready, which seems to me rather safe
http://gcc.gnu.org/ml/gcc-patches/2004-12/msg02003.html
Paolo.

Did I already open a PR for this misbehaviour in the past? What

Hi again! Yes, I can confirm that the patch works fine here: regtests ok and
both the above testcase and the below pass with it, which basically amounts
to making possible a decent implementation of tr1::type_traits::aligned_storage
Thanks Giovanni! Please post your complete work ASAP and let's have this fixed
for 4.0 too, if possible!
//////////////////
struct A
{ typedef char type[4] __attribute__((aligned(4))); };
template<unsigned, unsigned>
struct B;
template<unsigned _Len>
struct B<_Len, 4>
{ typedef char type[_Len] __attribute__((aligned(4))); };
template<bool> struct StaticAssert;
template<> struct StaticAssert<true> {};
StaticAssert<__alignof__(A::type) == __alignof__(B<4, 4>::type)> a1;
StaticAssert<__alignof__(B<4, 4>::type) == 4> a2;

We lose the alignment while tsubsting. This is a quick patch for this, I'm not
sure if there are other information we should propagate from the original array
type to the new array type, I guess the reviewer will know.
Meanwhile, Paolo, mind if I ask you to test this patch for me? You can also
test the partial specialization, it looks like it works for me.
