[Parted-maintainers] Bug#991263: libparted2: libparted assertion fails on resizing a certain sun partition table

[Rich Ercolani]

Package: libparted2
Version: 3.4-1
Severity: normal
X-Debbugs-Cc: rincebrain at gmail.com

Like it says on the tin - I noticed my drive's partition table was smaller than the drive,
tried to resizepart, and boom.

I'm assuming I input a somehow invalid value, but an assertion failure was not the outcome
I expected.

Entire chain of events:

$ sudo parted /dev/sda
