    p = buf1;
    for(j = 0;j < 10; j++) {
        for(i = 0;i < 10; i++) {
            w = *p;
            if(w != 1) {
                w = buf2[p - buf1];
                b(i*2+1, j, w);

It works for me on x86_64 with -m64 and -m32.  I'm trying with native 
32bit now.

------- Comment #8 from rguenth at gcc dot gnu dot org  2008-05-16 09:10 -------
Works for me as well.

./xgcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4_3-branch/configure --enable-languages=c,c++,fortran
--enable-checking --disable-bootstrap
Thread model: posix
gcc version 4.3.1 20080516 (prerelease) (GCC) 

also for http://gcc.gnu.org/ml/gcc-testresults/2008-05/msg01383.html

So I guess 4.3.1 is really fixed?  I'm now trying i686 for trunk ...

------- Comment #9 from rguenth at gcc dot gnu dot org  2008-05-16 10:00 -------
So on the trunk we have the same issue, we get a non-pointer parts->base.

We have the affine combination

{
  type = unsigned int
  offset = 0
  elements = {
    [0] = &buf2 * 1, 
    [1] = p_36 * 1, 
    [2] = &buf1 * 18446744073709551615, 
    [3] = i_48 * 1
  }
}
