grub dumps core

[Harald Dunkel]

Hi folks,

I get a core dump if I try to install grub on an USB stick
(amd64). Sample session:

# mount -t reiserfs /dev/sdd1 /mnt
# grub-install --root-directory=/mnt --no-floppy /dev/sdd
/usr/local/sbin/grub-install: line 458: 32514 Segmentation fault      (core dumped) 
$grub_shell --batch $no_floppy --device-map=$device_map  >$log_file <<EOF
root $root_drive
setup $force_lba --stage2=$grubdir/stage2 --prefix=$grub_prefix $install_drive
quit
EOF

Installation finished. No error reported.
This is the contents of the device map /mnt/boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0)   /dev/sda
(hd1)   /dev/sdd



Please note that the error is not caught by the grub-install
script. The boot sector on /dev/sdd is not changed. If I
try to manually install grub within gdb, then I get

This is the current CVS version. I get the same problem with
grub included with Debian Unstable.

Anybody got an idea?
