[Message part 1 (text/plain, inline)]

My system is Debian testing and kernel version "Linux version 4.7.0-1-
amd64 (debian-kernel <at> lists.debian.org) (gcc version 5.4.1 20160904
(Debian 5.4.1-2) ) #1 SMP Debian 4.7.8-1 (2016-10-19)". 

GNU Parted has version 3.2.

I reordered partitions to their natural order using fdisk. After
rebooting and using gparted (or parted) I get an error with
message "Assertion (metadata_length > 0) at
../../../libparted/labels/dos.c:2313 in function
add_logical_part_metadata() failed".

"partprobe /dev/sda" tells me that "A bug has been detected in GNU
Parted...Please email a bug report to bug-parted <at> gnu.org", which I am
dutifully doing.

Kind regards

Hans Peter

Finally, a clue as to how people are having this happen.  I have no idea
why fdisk has that option or why anyone would ever use it, but it seems
like that is the culprit for ending up with these goofy partition
tables.  Please provide the output of fdisk -l, as well as dd
if=/dev/sda count=1 | hd.
