dd segfaults on amd64

Bug #30088 reported by Tobi Vollebregt on 2006-01-30
Affects Status Importance Assigned to Milestone
coreutils (Ubuntu)

Bug Description

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.

I can't reproduce this on Dapper AMD64.

I think the backtrace would be welcome, and more informations about your system too.

hm, I just tried it again, and it doesn't crash anymore. Maybe it has been fixed. It did crash earlier this week with my Flight-4 Live CD while backupping/restoring the MBR. So I'll assume it has been fixed by some update of dd sometime between Flight 4 and Flight 5. If I manage to reproduce it again, I'll reopen the bug.
