bug report

Dear Parted-Team,

Using GNU Parted 1.4.10 (actually your boot disk version 2),
I successfully resized the Windows partition of a Seagate 40 GB drive,
model ST340823A, and then entered these commands to add new partitions:

> (parted) mkpartfs primary FAT 7012.749 8032.500
> (parted) mkpartfs logical FAT 8032.500 19077.187
> (parted) mkpartfs logical FAT 19077.187 20096.938
> (parted) mkpartfs logical ext2 20096.938 20606.813
> (parted) mkpartfs logical linux-swap 20606.813 20732.321
> (parted) mkpartfs logical ext2 20732.321 24827.013

Upon viewing the newly created partitions with the latest version
of the 'Ranish Partition Manager', I got error messages saying that
several partitions (apparently the Logical Partitions) overlap
another partition. So, I inspected the Partition Sectors of the
Logical Partitions, and found out that the second record of each
Partition Table specifies the number of sectors in a way that all of
the remaining space of the Extended Partition is allocated to the
respective Logical Partition, which indeed constitutes overlapping
partitions:

As far as I know, the 'traditional' way of specifying the number of
sectors in those partition records which link the Logical Partitions
would yield these table entries for my partition layout:

>     #  HD  FS    Cyl Head Sect    Cyl Head Sect      sector     sectors

With these entries, there are no more error messages.

Please leave me a short note as to whether you consider to change
Parted's way of specifying partition sizes accordingly -- or did I chase
a pseudo-bug?

Kind regards,
