Hello!

I can't make sun partition table with parted over existing one on
debian sparc64 physical machine Sun SPARC T5120:

I don't know how the sun disklabel works, so it might blow up in a
shower of sparks, but you might try commenting out that assert and see
if it works.  See if you can manipulate the existing partition table
too, before creating a new one.

just tried to create a new partition and remove it after - works.

tried to compile parted.git , but it failed:

the only way to compile parted for me , is to pass
--disable-gcc-warnings to configure.
Creating a new partition and removing it with git compiled parted works.

Commenting out PED_ASSERT at libparted/labels/sun.c , line 189 , and
compiling again, allow to create sun/gpt/msdos labels.

(after msdos label has been created)
