parted segfault ...

[Timshel Knoll]

Hi,

I was mucking around with parted and found a couple of problems, before
I found a segfault ...

Firstly: /dev/hdb3 is _not_ a sun-ufs disklabel, it is an OpenBSD
disklabel (and recognised by the kernel as such) - from dmesg:

Partition check:
 hda: hda2 hda3 < hda5 hda6 hda7 hda8 >
 hdb: hdb1 hdb2 < hdb5 > hdb3
 hdb3: <bsd: hdb6 hdb7 hdb8 hdb9 hdb10 >
        ^^^

Second:
I compiled a debug version and did a backtrace:

...
(parted) print
No Implementation: The sun-ufs file system code doesn't support loop
disk
labels.
Ignore Cancel ? c

Program received signal SIGSEGV, Segmentation fault.

Hmmm ... that doesn't look right :-)

If you need any details about the disklabel, let me know .....

Thanks,
