[ale] fsck

Has anybody ever had any problems with fsck throwing a SIGFPE when run
on a damaged ext2 partition?

spoo:/home/jbayes# fsck /dev/hda1
Parallelizing fsck version 1.13 (15-Dec-98)
e2fsck 1.13, 15-Dec-98 for EXT2 FS 0.5b, 95/08/09
Couldn't find ext2 superblock, trying backup blocks...
Warning... fsck.ext2 for device /dev/hda1 exited with signal 8.
spoo:/home/jbayes# fsck -b 8193 /dev/hda1
Parallelizing fsck version 1.13 (15-Dec-98)

It works fine when run on sda[1-6] (even when sda2 was damaged), and
it used to work fine on hda1 and 2. But this afternoon I got a garbage
output when I did an ls, and when I fscked hda1 I got the SIGFPE.

I tried debugfs, but it won't open the device if the superblock is
bad. 

Any ideas?
