assertion PED_LE64_TO_CPU (gpt->AlternateLBA) <= disk->dev->length failed

[Bjorn Helgaas]

[I tried to submit this via Trac, but it said "500 Internal Server Error
(Submission rejected as potential spam)"].

I also tried to debug this with gdb, but the parted I built complains
like this:
  $ /usr/local/sbin/parted ../rhel5.2-image
  /usr/local/sbin/parted: error while loading shared libraries: 
libparted-1.8.so.8: cannot open shared object file: No such file or directory

The trace below is from the the compiled but not installed tool.

I installed RHEL5.2 on an ia64 system, resulting in /dev/sda1 (a 100MB FAT 
partition containing the bootloader, kernel, etc) and /dev/sda2 (the 4GB root 
filesystem).  I used dd to copy the first 5GB of /dev/sda to the file 
rhel5.2-image.

The GPT scheme keeps a secondary copy of the partition table at the
end of the disk.  My rhel5.2-image file is obviously missing that,
since it only contains the first 5GB of the disk image.  That might
explain this assertion failure.

But I hope parted can handle this situation more gracefully.

Anyway, I copied rhel5.2-image to an x86 system and ran parted on it:

$ parted/parted ../rhel5.2-image print
