I was referring to that patch in the previous message. In the misaligned case, the code will always do two 8-byte loads if the dest misalignment is greater than the src misalignment even with your patch applied. This will segfault when count == 1 and src is on a page boundary. Another check needs to be added before the first branch to $u_head to fix this. -- Debian GNU/Linux 3.0 is out!
