Package: util-linux
Version: 2.17.2-9
File: /sbin/cfdisk
Severity: normal
The cfdisk program in Debian/Squeeze segfaults when i try to write a
new partition table to a RAID disk. The disk size is 7 809 794 048
kilobytes, and I try to create a LVM (8e) primary partition filling
the entire disk. The created partition end up being only 1 367 339
929 kilobytes. When I ask cfdisk to create it, its partition view
show the new partition filling the entire disk. But when I ask it to
write the partition table, it segfaults. I run cfdisk with the
nb_NO.UTF-8 locale, and seeing the valgrind report I suspect this
might be related.
Here is the valgrind output from a test run.

Version: 2.25-1
Hello!
The new util-linux v2.25 contains a completely rewritten cfdisk program
which is now based on the new (lib)fdisk code. This means cfdisk should
now work equally well as the new fdisk and hopefully the reported bug
should be gone.
If you still see the problem you originally reported with the new version
then please do reopen the bug report and provide some additional information
about it.
Regards,
Andreas Henriksson
