Why has this align any effect at all? gcc's documentation says: "The `aligned' attribute can only increase the alignment; but you can decrease it by specifying `packed' as well." And as the struct has pointers in it, I'd guess it already had a 64-bit alignment unless there is some "packed" hidden somewhere. Bernhard R.
