The problem is that fold figures sth out that tree-affine doesn't. The
latter doesn't simplify
{
type = long unsigned int
offset = 0
elements = {
[0] = &A[(long unsigned int) (long unsigned int) ((i_3(D) + -1) * 16) + 20]
* 1,
[1] = (long unsigned int) ((i_3(D) + -1) * 16) *
340282366920938463463374607431768211455,
[2] = ivtmp.9_20 * 1
}
}
to just &A[20] + ivtmp.9_20.
Now we can avoid the ICE by gimplifying the address properly which we don't
because of a typo I made in an earlier change.
