dd segfaults on amd64

dd segfaults on amd64 when just before it should show the message "XX bytes transferred in YY seconds (ZZ bytes/sec)".

It happens no matter what I set the blocksize to.

This bug can be reproduced by doing, on an amd64 architecture PC:

tobi@ubuntu:~$ echo "hello world" > file1
tobi@ubuntu:~$ dd if=file1 of=file2
0+1 records in
0+1 records out
Segmentatie fout

On the same amd64 computer, but in a 32 bit chroot:

tobi@ubuntu:~$ dd if=file1 of=file2
0+1 records in
0+1 records out
12 bytes transferred in 0.000207 seconds (57968 bytes/sec)

If a backtrace is needed because you can't reproduce the bug just ask and I'll provide one.
