I thought of your application - this which uses the __aligned__
attribute.

But I've just tried your test on an amd64/Linux box with gcc-4.2,
with the alignment set to 4096. It doesn't work - the pointer
is 16-byte aligned but not more. So it might well be that
a large alignment attribute has no effect.
(amd64 is different anyway because its ABI defines the stack
alignment, but I don't have an i386 with gcc>4.1 atm.)

best regards
Matthias
