I tested on i686 (-march=athlon-xp -O2) with gcc 4.3 revision 132072 (older
than the one I tried at arm), and it seems to misbehave there.
I'm not sure tought of the implications, since that's a superscalar cpu and
these things are too complicated to my mind, perhaps it's faster that way
because of an eventual alignment, etc... But it seems buggy to me :-)
