1.6.5pre1: segmentation fault in disk_sync_part_table

[Sven Hartrumpf]

Hi again.

I see reproducable crashes for 1.6.5-pre1 (I think 1.6.3 crashes similarly).
For example, the following:
(parted has been configured like this:
./configure --prefix=/programs/free/parted-1.6.5-pre1 --enable-all-static
OS: SuSE GNU/Linux 7.2, I386, kernel 2.4.20-rc1 )

(gdb) run

Using /dev/hde
Information: The operating system thinks the geometry on /dev/hde is      
5005/255/63.  Therefore, cylinder 1024 ends at 8032.499M.

The space where I put the extended partition comes from a primary partition
(linux-swap) that I deleted with "rm" (this swap space was not used any more,
checked with swapon -s). BTW: the "rm" was successful but crashed similarly
to "mkpart".


After restart I get

(parted) p

and I hope that everything is fine.
